<p>Creating realistic fire VFX doesn't have to mean expensive simulations or endless render times. With the right assets — and the right approach — you can build cinematic fire entirely in post. And if you’re just getting started or want a testbed to practice your comp, the <a href="https://bit.ly/3AAwUlL">ActionVFX Practice Footage Library</a> is a great place to start.</p>
<p>These free, production-style plates let you hone your skills on real-world footage without the licensing headaches — and they’re perfect for testing fire composites, light interactions, and scene-building workflows.</p>
<p>Now let’s break down what makes fire believable — and how to make it work in your shots using only ActionVFX stock elements.

<h3>1. Skip the Sim — Use Real Fire Footage</h3>
<p>Simulations can be time-consuming and unpredictable. If you’re working solo or on a tight deadline, pre-keyed fire footage saves you hours of work — and arguably delivers a more realistic result. That’s because these elements were captured in-camera, under real lighting, with natural physics baked in.</p>
<p>ActionVFX fire bursts, ground fire, embers, and smoke layers build a multi-depth composite. Real fire footage doesn’t just look better, it behaves better.</p>
<h3>2. Start With a Solid Camera Track</h3>
<p>This is crucial. If your scene has camera movement — especially handheld — a 2D planar track isn’t enough. Fire needs to move with the environment. In this shot, the artist used a full 3D camera solve via SynthEyes, but most software (After Effects, Blender, Nuke, Resolve) has built-in 3D tracking tools.</p>
<p>The goal is to lock your fire to the world, not the frame. Even slight parallax issues will break the illusion.</p>
<h3>3. Roto Your Foreground — It’s Worth It</h3>
<p>Even if you’re not doing face replacement or keying, rotoscoping is essential in fire composites. Without it, your flames sit awkwardly on top of the subject, destroying the depth of your scene. In this tutorial, the subject was rotoscoped using a simple mask — enough to let fire elements slip behind and “live” inside the shot.</p>
<p><strong>Pro tip</strong>: keep your roto loose if the fire is fast-moving. It adds to the realism and saves time.</p>
<h3>4. Relight the Subject — This Is What Sells It</h3>
<p>This is where most fire composites fall apart — the fire is there, but the subject doesn’t react to it. Real fire is dynamic. It flickers, it wraps, and it casts light that moves. If your character isn’t being lit by the flames, the whole illusion breaks.</p>
<p><strong>How to do it?</strong>
First, the footage was brought into DaVinci Resolve Studio, where a Depth Map was generated to isolate the subject from the background.</p>
<ol>
<li>
<p>Using that depth information, the scene was exported as two relight maps — one from the left and one from the right — to simulate firelight wrapping around the actor.</p>
</li>
<li>
<p>Back in After Effects, each relight map was placed above the footage and set to Add blend mode.</p>
</li>
<li>
<p>Each layer was tinted with a warm fire hue (orange/yellow) to match the flame source.</p>
</li>
<li>
<p>Then a wiggle expression was applied to the opacity, simulating the chaotic, unpredictable flicker of real fire.</p>
</li>
</ol>
<p>This technique creates a reactive lighting effect that behaves more like practical on-set fire — shifting intensity and casting realistic color back onto the actor. It also allows you to control the timing and behavior of each light pass independently, adding nuance and depth.</p>
<p><img src="https://a-us.storyblok.com/f/1002378/4096x2160/da3a589628/pf0086-01_clip-1_bmdgen5_4k-5-36-53-16-trer.jpg" alt=""></p>
<h3>5. Don’t Skip the Glow Pass</h3>
<p>This technique adds depth and scale. In the example, the artist uses a soft, warm glow just behind the masked subject to simulate light spill and ambient fire bloom.</p>
<p>It anchors the fire to the environment and makes it feel like it’s really pushing out light and heat.</p>
<h3>6. Distortion, Sparks, and Smoke — Fire’s Real Behavior</h3>
<p>To go beyond just “looking hot,” your fire composite needs environmental reaction.
In this shot, that includes:</p>
<ul>
<li><strong>Heat distortion</strong>: subtle warp to mimic rising heat</li>
<li><strong>Floating embers</strong>: drifting sparks give a sense of atmosphere and movement</li>
<li><strong>Smoke layering</strong>: softens edges and fills the volume</li>
</ul>
<p>Use distortion sparingly — too much can ruin your plate — but it’s essential for high-heat shots.</p>
<h3>7. Match Your Grade (Then Grade It Again)</h3>
<p>Trying to force each fire clip to match your plate can lead to inconsistency. Instead, build your composite first — fire, glow, light, smoke, distortion — then apply a unified color grade on top.</p>
<p>This brings everything into the same color space, simulates lens behavior, and helps your composite feel like one shot, not layers stacked together.</p>

ActionVFX's First Ever Course!

Introduction to ComfyUI For VFX By Doug Hogan

<p>You know that feeling when your smoke asset just sits there like a sad layer on top of your shot? No shadows, no light interaction.</p>
<p>Yeah. I was sick of that too.</p>
<p>Here's how to relight 2D smoke assets in After Effects so it actually reacts to fire. You get real lighting falloff, dynamic shadows, and it doesn’t look like you slapped it on in 30 seconds.</p>
<p>Here’s how you can do it using just two free plugins and a couple free ActionVFX assets.</p>
<p>You'll want to watch the video for a full walkthrough and to get the <em>why</em> behind the techniques I use. But I went ahead and put a summary of each step below so you have that for reference.</p>
<p><iframe width="560" height="315" src="https://www.youtube.com/embed/pV8NCLWLefc" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></p>
<h2>Step 1: Plugins You’ll Need</h2>
<p>This whole trick depends on two things:</p>
<ul>
<li><strong><a href="https://bit.ly/normal-mapper-for-ae">Normal Mapper for AE</a></strong> (free on aescripts—but I encourage you to donate to the creator)</li>
<li><strong><a href="https://bit.ly/normality-plugin">Normality</a></strong> by Stefan Minning (also free)</li>
</ul>
<h2>Step 2: The Setup</h2>
<p>Everything I used is included with your ActionVFX subscription, but you can also follow along with free assets too:</p>
<ul>
<li><strong><a href="https://bit.ly/4jUWfJ7">Smoke Plume:</a></strong> from the Free Smoke Plumes Collection</li>
<li><strong><a href="https://bit.ly/3SC81fa">Practice Plate:</a></strong> from the Practice Footage Library</li>
</ul>
<p>You can also get the fire asset I used with the code in the video until May 29th, 2025. <a href="https://bit.ly/430OA64">Just input the code here</a>.</p>
<p>I set everything up in After Effects using an ACES workflow. If you're not familiar with ACES in AE, <a href="https://www.actionvfx.com/blog/how-to-use-aces-in-after-effects">we’ve got a separate video walking you through that</a>.</p>
<h2>Step 3: Precomposing the Smoke</h2>
<p>Precomp the smoke layer and call it <strong>Relit Smoke</strong>. From here, there are two ways you can go:</p>
<ul>
<li><strong>Option 1:</strong> Leave all attributes in Master Comp – better for static shots or stationary lights (like a fire).</li>
<li><strong>Option 2:</strong> Move all attributes into new comp – better if you have moving lights (like headlights sweeping across).</li>
</ul>
<p>For this walkthrough, I started with Option 1.</p>
<h2>Step 4: Building the Normal and Depth Maps</h2>
<p>Inside the Relit Smoke comp, duplicate the smoke layer 4 times:</p>
<ul>
<li><strong>Normality</strong> (top)</li>
<li><strong>Depth Map</strong></li>
<li><strong>Normal Map</strong></li>
<li><strong>Texture</strong></li>
</ul>
<p>Each of these layers gets its own treatment:</p>
<ul>
<li><strong>Depth Map:</strong> Invert → Curves → Adjust until clipping shows in the highlights.</li>
<li><strong>Normal Map:</strong> Precomp it, then apply Normal Mapper and crank the strength to 100. Add a Fast Box Blur (~1.2–1.5) to clean up artifacts.</li>
<li><strong>Texture:</strong> Invert → Unmult → Invert again. Then adjust alpha with Curves and add a Tint to ensure grayscale.</li>
</ul>
<h2>Step 5: Bringing It All Together</h2>
<p>On the Normality layer apply:</p>
<ul>
<li>Invert → Unmult → <strong>Normality plugin</strong></li>
</ul>
<p>Set it to 3D (even though Normality doesn’t recommend it) because it gives you better falloff and placement.</p>
<p>Then assign:</p>
<ul>
<li><strong>Normal Map</strong> from the precomp</li>
<li><strong>Depth Map</strong> from the comp</li>
</ul>
<p>Make sure <strong>Effects &amp; Masks</strong> is checked.
Invert the Depth Map so thinner smoke appears brighter (as it should when light passes through it).</p>
<h2>Step 6: Lighting the Smoke</h2>
<p>Now for the fun part: lighting.</p>
<p>Create a <strong>Point Light</strong>, set it to white, and position it where the fire would realistically be.</p>
<p>Then duplicate it and move the second one to the opposite side for more natural coverage.</p>
<p>To make the lights feel alive (like fire), add wiggle expressions:</p>
<ul>
<li><strong>Y Position:</strong> wiggle(3,60)</li>
<li><strong>Z Position:</strong> wiggle(2,100)</li>
</ul>
<p>Copy those expressions to both lights. The result? Lights that move organically like a fire would—casting shadows and highlights across the smoke dynamically.</p>
<h2>Step 7: Making It Fit the Scene</h2>
<p>Back in the main comp, duplicate and offset the smoke to make it wider, covering more of the fire area. Relink the depth and normal maps for each instance.</p>
<p>You might notice the smoke is now moving too slow compared to the fire—so use <strong>Time Stretch</strong> on the precomp and set it to <strong>30</strong>.</p>
<h2>Step 8: Coloring the Smoke with Firelight</h2>
<p>Here’s where it really sells.</p>
<p>Duplicate the relit smoke precomp and add a <strong>Fill</strong> effect to the bottom one (set to black for black smoke).</p>
<p>Then duplicate the fire layer, apply a glow (I used Deep Glow V2, but standard Glow works too), set the <strong>Source Opacity to 0</strong>, and then track matted the glow layer to the relit smoke using <strong>Luma Matte</strong>.</p>
<p>Boom. Orange-tinted smoke that shifts color with the flickering fire.</p>
<p>You could technically just apply a Tint to the smoke and call it a day—but doing it this way means the light interacts dynamically with the smoke, based on the actual fire movement.</p>
<h2>Step 9: Bonus Lighting</h2>
<p>Need moonlight on the smoke too? Easy.</p>
<p>Just duplicate your relighting comp in the project panel, move the lights to match the moonlight position, and drag the duplicate into the main comp. Hold <strong>Alt</strong> while you drop it on top of the relit smoke layer to swap them.</p>
<p>Set the blending mode to <strong>Screen</strong>, add a <strong>Tint</strong>, and now you’ve got moonlight hitting your smoke too.</p>
<h2>Final Touches</h2>
<p>From there it’s all about dialing it in:</p>
<ul>
<li>Adjust curves, hue/sat, exposure.</li>
<li>Move lights around.</li>
<li>Edit the normal or depth map if something feels off.</li>
<li>Add glow, camera shake, you name it.</li>
</ul>
<p>You’re not locked into anything. The beauty of this method is it’s totally tweakable.</p>
<h2>Why This Method Works</h2>
<p>You’re taking 2D stock footage and tricking After Effects into treating it like 3D volumetrics—without ever leaving AE, and without needing full-on simulations.</p>
<p>And if you’re working on tight timelines or client work that doesn’t justify the Houdini pipeline? This will save you.</p>

<p>If you’ve ever keyed out a green screen and ended up with your actor looking like they just stepped out of a toxic waste barrel — yeah, I’ve been there too.</p>
<p>That’s also a great way to make the audience go, <em>“Oh... that’s fake.”</em>
Which is also a great way to make your client or supervisor go, <em>“Hey, you’re fired.”</em></p>
<p>So let’s fix that.</p>
<p>If you want your composites to look realistic, getting a clean key is non-negotiable. In this tutorial, we’ll walk through 5 key tips (pun unfortunately intended) for better chroma key results — using After Effects and Keylight as our tool of choice.</p>
<p><iframe width="560" height="315" src="https://www.youtube.com/embed/L1_Wx-IxsAA" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></p>
<h2>Use a Properly Lit Green Screen</h2>
<p>Before you even touch your software, the most important factor in getting a clean key is how your footage was shot.</p>
<p>First rule: <strong>make sure your green screen is evenly lit.</strong> No shadows, no bright spots, no weird gradients creeping across the background. Just a clean, flat green. Uneven lighting is one of the biggest causes of fringing and artifacts during keying.</p>
<p>Next, think about distance. The closer your subject is to the screen, the more green spill is going to bounce onto them. By giving your subject more space from the background, you cut down on that glow before it even starts — and your keyer will have a much easier time.</p>
<blockquote></blockquote>
<p><strong>Bonus:</strong> Need some properly shot green screen footage to practice with? We've got a free <a href="https://www.actionvfx.com/practice-footage">Practice Footage Library</a>. It has several green screen shots to help you practicing keying and compositing.</p>
<h2>When to Use a Blue Screen Instead of a Green Screen</h2>
<p>In most cases, green screens are the go-to. They tend to key out cleanly in daylight scenes and play nice with natural lighting.</p>
<p>But there are times when blue makes more sense:</p>
<ul>
<li>If your actor is wearing green, obviously.</li>
<li>If you’re shooting a nighttime or low-light scene — blue screens retain shadows better and preserve more detail in dark areas.</li>
</ul>
<p>So if green’s giving you trouble, it might not be your fault. Switch colors when it makes sense.</p>
<h2>How to Use Keylight in After Effects</h2>
<p>Once you’ve got solid footage, it’s time to key — and if you’re in After Effects, Keylight is your friend. It’s powerful, free, and built right in.</p>
<p>Here's a quick breakdown:</p>
<ul>
<li><strong>Screen Colour:</strong> Use the eyedropper to select your background.</li>
<li><strong>Screen Gain:</strong> Controls how aggressive the key is. Higher = more background removal (and more danger to your subject).</li>
<li><strong>Screen Balance:</strong> Helps fix uneven lighting by adjusting the color channels.</li>
<li><strong>Clip Black / Clip White:</strong> Fine-tune the matte edges. Clip Black removes leftover junk; Clip White locks in the solids.</li>
<li><strong>Screen Matte View:</strong> Flip to this mode to see your alpha channel. It’ll show you what’s really being keyed — which is super helpful for fixing trouble spots.</li>
</ul>
<p>Take your time here. Zoom in. Toggle between modes. This is where <em>“meh”</em> keys become production-ready.</p>
<h2>Kill the Spill</h2>
<p>Even with solid footage and a clean matte, green spill happens — especially around hair, fabric edges, or shiny surfaces.</p>
<ul>
<li>Keylight has built-in spill suppression controls. Use them.</li>
<li>Tweak these <strong>after</strong> your matte is dialed in.</li>
<li>Desaturate or rebalance the edges to neutral tones.</li>
<li>Watch out for skin tones — don’t trade green glow for zombie skin.</li>
</ul>
<h2>Garbage Mattes: Not Glamorous, But Super Useful</h2>
<p>Garbage mattes help your keyer focus only on the subject. That means:</p>
<ul>
<li>Faster rendering</li>
<li>Less chance of noise and edge errorsFinal Polish: Matte Cleanup &amp; Edge Refinement
Once your key is mostly working, flip back to Screen Matte View and check your edges.</li>
</ul>
<h2>Final Polish: Matte Cleanup &amp; Edge Refinement</h2>
<p>Once your key is mostly working, flip back to <strong>Screen Matte View</strong> and check your edges.</p>
<ul>
<li>Use Clip Black/White to tighten things up.</li>
<li>Look for semi-transparent fuzz or inconsistent edges — especially in hair or fine detail.</li>
<li>You want clean, solid separation. No gray halos. No crunchy outlines.</li>
</ul>
<p>This last step takes time, but it’s the difference between <em>“that’s obviously keyed”</em> and <em>“wait... that’s composited?”</em></p>

How to Fix Bad Green Screen Footage | Pro Chroma Key Tips for Cleaner VFX

<p>You probably didn’t become a VFX artist because you love rotoscoping.</p>
<p><a href="http://actionvfx.com/blog/introduction-to-rotoscoping-in-nuke">Frame-by-frame roto</a> is one of the most tedious tasks in compositing—especially when dealing with hair, fast motion, or complex shapes. But what if Nuke could learn how to do it for you?</p>
<p>That’s where <strong>CopyCat</strong> comes in. With the right setup, you can train your own AI model to generate mattes automatically, saving hours of manual work.</p>
<h2>How to Train CopyCat for Rotoscoping</h2>
<p><a href="https://learn.foundry.com/nuke/content/reference_guide/air_nodes/copycat.html">CopyCat</a> works by analyzing a small set of hand-rotoscoped frames and learning to apply that same matte extraction across an entire shot. The key to getting great results? Training it properly. Here’s how:</p>
<p><img src="https://a-us.storyblok.com/f/1002378/1920x1080/cb1d88a6da/nuke-node-graph-manual-rotoscope.jpg" alt=""></p>
<h3>1. Roto a Few Key Frames</h3>
<p>Before CopyCat can generate mattes, it needs training data—clean mattes that show it what to learn.</p>
<ul>
<li>Pick <strong>5–10 unique keyframes</strong> throughout your shot. Choose frames where the subject’s shape varies the most (e.g., different poses or angles).</li>
<li>Create precise mattes using Nuke’s standard roto tools. The better these keyframes, the better CopyCat will perform.</li>
</ul>
<p><em>Example</em>: If you’re rotoscoping a person running, choose frames where their legs are in different positions.</p>
<p>If you're still learning the basics of Nuke, here's a great intro to Nuke rotoscoping:

<h3>2. Set Up and Train CopyCat</h3>
<p>Once you have your training frames, it’s time to set up the CopyCat node.</p>
<ul>
<li>Add a <strong>CopyCat node</strong> to your Nuke script.</li>
<li>Connect your original footage to the <strong>Input</strong> and your hand-made mattes to the <strong>Ground Truth</strong> input.</li>
</ul>
<p>Next, adjust your training settings:</p>
<ul>
<li>Start with low iterations (<strong>~1000-2000</strong>) for quick tests.</li>
<li>If the results are good, increase iterations.</li>

Learn Nuke in this free 6-part course by Doug Hogan, starting with the fundamentals and building up to professional techniques.

Master Nuke Compositing: Free Introduction Course to Nuke

<p>If you’re an ActionVFX user working in Adobe After Effects, you might have run into issues with certain assets in the DRAGONcolor2 / REDgamma4 color space. Since After Effects doesn’t natively support this format, getting the most out of these assets requires a few extra steps.</p>
<p>In this guide, we’ll walk you through how to properly <strong>interpret, transform, and composite DRAGONcolor2 assets</strong> while keeping all the original data intact.</p>
<h2>Why Some Assets Use DRAGONcolor2 / REDgamma4</h2>
<p>Many of our older assets were filmed on RED DSMC2 cameras, which used DRAGONcolor2 / REDgamma4 to retain as much data as possible. While this was a great choice for quality, Adobe After Effects doesn’t play nice with this color space—meaning your assets may look washed out or incorrect when imported. You might notice this on our older pyro collections like Window Fire or Gas Explosions Vol. 1, among a few others.</p>
<p><strong>The good news? There's an easy way to fix this thanks to our friends at RED.</strong></p>
<p><img src="https://a-us.storyblok.com/f/1002378/900x506/61233150cf/red-camera-bts.jpg" alt=""></p>
<h2>The Fix: Custom LUTs from RED</h2>
<p>To solve this issue, RED developed <strong>custom LUTs specifically for ActionVFX users</strong>. These LUTs convert different RED gammas into a more usable format, making compositing in After Effects much easier.</p>
<p>🔥 <strong>Pro Tip:</strong> You can <a href="https://s3.us-east-1.amazonaws.com/uploads.actionvfx.com/public_downloads/REDGammaLUTs_64x_v02.zip">download these LUTs for free here</a>.</p>
<p><strong>Before you get started</strong>, if you're not familiar with ACES color management and how it streamlines compositing, you'll need to check out our <strong><a href="https://actionvfx.com/blog/how-to-use-aces-in-after-effects">ACES guide</a></strong> first.</p>
<h2>How to Set Up DRAGONcolor2 / REDgamma4 Assets in After Effects</h2>
<p>Follow these steps to properly set up your assets and maintain full color accuracy.</p>
<p>You can follow step-by-step along with Sam in our tutorial:
<iframe width="560" height="315" src="https://www.youtube.com/embed/q249a3SH320" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></p>
<p><strong>1. Set the Correct Input Color Space</strong></p>
<ul>
<li>Right-click your asset in the Project Window → <strong>Interpret Footage &gt; Main</strong></li>
<li>Go to the <strong>Color Tab</strong></li>
<li>Under Override Media Color Space, select: <strong>Input/RED/Input - RED - Linear - DRAGONcolor2</strong></li>
</ul>
<p>At this point, the colors will still look off—but don’t worry, we’re about to fix that.</p>
<p><strong>2. Apply the RED LUT in Lumetri</strong></p>
<ul>
<li>Add the <strong>Lumetri Color</strong> effect to your asset</li>
<li>Under <strong>Basic Correction</strong>, locate the <strong>Input LUT</strong> option</li>
</ul>
<p>Instead of using the default presets, we need to add one of the custom LUTs:</p>
<ul>
<li>Open <strong>File Explorer</strong></li>
<li>For Windows, navigate to: <strong>Local Disk &gt; Program Files &gt; Adobe &gt; Adobe After Effects &gt; Support Files &gt; Lumetri &gt; LUTs &gt; Technical</strong></li>
<li>For Mac navigate to: <strong>Macintosh HD &gt; Applications &gt; Adobe After Effects &gt; Adobe After Effects.app (right click to “Show Package Contents”) &gt; Lumetri &gt; LUTs &gt; Technical</strong></li>
<li>Drag and drop the <strong>RG4_2_LIN_64.cube LUT</strong> from the RED LUT pack into this folder</li>
<li>Restart After Effects</li>
<li>Now, in Lumetri’s <strong>Input LUT</strong> section, select <strong>RG4_2_LIN_64</strong></li>
</ul>
<p>Once applied, your footage will now display correctly in <a href="https://actionvfx.com/blog/how-to-use-aces-in-after-effects">ACES</a>, retaining all of its original data for proper compositing. Once the LUT is added to the correct folder, it will always be available in future projects.</p>
<h2>Making This Process Even Faster</h2>
<p>If you’re working with a lot of our DRAGONcolor2 / REDgamma4 assets in the same project, you can <strong>save time by applying your initial footage interpretations to multiple files at once.</strong></p>
<p><strong>Use “Remember Interpretation”</strong></p>
<ul>
<li>After setting up one asset, right-click it in the Project Window</li>
<li>Select <strong>Interpret Footage &gt; Remember Interpretation</strong></li>
<li>Now, apply this interpretation to multiple assets at once by selecting them, right-clicking, and choosing <strong>Apply Interpretation</strong></li>
<li>Add Lumetri once the asset is in your Comp</li>
<li>Select your <strong>RG4_2_LIN_64 LUT</strong> as your Input LUT</li>
</ul>
<p>Final Thoughts
By following this workflow, you’ll ensure your DRAGONcolor2 / REDgamma4 assets composite seamlessly into your After Effects projects without any color issues.</p>

<p>Have you ever struggled to get VFX elements to blend seamlessly into your scene? The key to pro-level compositing isn’t just <a href="https://www.actionvfx.com/blog/after-effects-quick-tip-how-to-light-your-vfx-elements-using-normal-pass">lighting</a> or effects—it’s understanding color spaces.</p>
<p>In our latest video, Sam breaks down how color spaces impact your composite and why ACES (Academy Color Encoding System) is a game-changer for standardizing colors across different assets.</p>
<p><iframe width="560" height="315" src="https://www.youtube.com/embed/pYzN_g-1N_w" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></p>
<h2>Why Color Spaces Matter</h2>
<p>Cameras, monitors, and software all interpret colors differently. If you’re using footage from multiple sources, mismatched color spaces can cause assets to look completely out of place. That’s where ACES comes in—it acts as a universal translator, ensuring all your elements exist in a consistent color space.</p>
<p>To understand this a little deeper, you can check out our blog on <a href="https://www.actionvfx.com/blog/the-difference-between-linear-and-logarithmic-color-space-and-why-you-should-care">linear and logarithmic color spaces</a>.</p>
<h2>How ACES Works in Compositing</h2>
<p>ACES uses input and output transforms to standardize footage:</p>
<ul>
<li>Input Transform – Converts your footage’s original color space into ACES.</li>
<li>Output Transform – Converts ACES footage back into the final deliverable color space.</li>
</ul>
<p>The best part? All major compositing software, including After Effects and Nuke, have the ACES workflow system built-in. You can preview your composite in your final delivery format while still working with high-quality data.</p>
<p>🔥 Pro Tip: After Effects doesn’t have a built-in transform for DRAGONcolor2 / REDgamma4 assets. <a href="https://actionvfx.com/blog/fix-color-issues-in-after-effects-free-luts">Check out our other blog to learn how to set it up properly.</a></p>
<h2>Setting Up ACES in After Effects</h2>
<p><strong>1. Change Project Settings</strong></p>
<ul>
<li>Go to <strong>File &gt; Project Settings &gt; Color</strong> and switch to <strong>OCIO Color Managed</strong>.</li>
</ul>
<p><strong>2. Set the Footage Input Color Space</strong></p>
<ul>
<li>Right-click footage → <strong>Interpret Footage &gt; Main &gt; Color tab</strong></li>
<li>Select the correct input transform (e.g., <strong>REDWideGamutRGB / REDLog3G10</strong>).</li>
</ul>
<p><strong>3. Blend Different Color Spaces Seamlessly</strong></p>
<ul>
<li>When working with multiple assets (e.g., <strong>Rec.709, DRAGONcolor2</strong>), use the correct transforms to unify their look.</li>
</ul>
<p><strong>4. Render in the Original Color Space</strong></p>
<ul>
<li>When exporting, set the Output Color Space to match your footage for easier grading.</li>
</ul>
<h2>Why ActionVFX Assets Are Built for ACES</h2>
<p>At ActionVFX, we provide assets in multiple color spaces—Rec.709, Linear, ACEScg, DRAGONcolor2, and more—so you can get the best data for your composite. We even list the color space on each product page, making it easy to match your workflow.</p>
<p>🔥 Pro Tip: Always check an asset’s color space before starting your composite. Otherwise, Sam might show up at your house to fix your input transform himself. (You’ve been warned.)</p>

How to Use ACES in After Effects (& Why Color Spaces Matter)

<p>The <em><a href="https://www.youtube.com/watch?v=a0JMSj5xdFk">Captain America: Brave New World</a></em> trailer showed off some intense action, including Red Hulk making a fiery entrance. In this tutorial, our very own Wyatt turned himself into Red Hulk in After Effects.</p>
<p>Learn how to make Hulk's glowing eyes, red skin, expanding hands, and ground-shattering impact.</p>
<p>The best part? You can do it all for just <strong>five credits or less</strong> using the ActionVFX library.</p>
<p><iframe width="560" height="315" src="https://www.youtube.com/embed/3SdkmysscnI" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></p>
<p><strong>Here's a quick rundown:</strong></p>
<h3>Step 1: Turning Your Skin Red</h3>
<p>The first thing we need to do is change skin color. Using After Effects, you can create this effect by:</p>
<ul>
<li>Duplicating your base footage</li>
<li>Using the <a href="https://www.actionvfx.com/blog/when-should-i-use-after-effects-roto-brush-tool">Roto Brush Tool</a> to isolate skin areas</li>
<li>Applying a Tint effect and mapping black/white values to a deep red</li>
<li>Adjusting brightness, contrast, and blending modes to make it look natural</li>
</ul>
<p>By keyframing the effect, you can make the transformation happen gradually, just like in the movies.</p>
<h3>Step 2: Adding Glowing Red Eyes</h3>
<p>No Hulk transformation is complete without those intense glowing eyes. Here’s how to do it:</p>
<ul>
<li>Mask out your eyes so they stay unaffected by the red skin tone</li>
<li>Import an ActionVFX <a href="https://www.actionvfx.com/collections/eye-textures-stock-footage">iris texture</a> (included in the Essentials Catalog)</li>
<li>Scale and position it over the eye and set the blend mode to Overlay</li>
<li>Use <a href="https://www.actionvfx.com/blog/how-to-do-motion-tracking-with-mocha-ae-beginner-friendly-after-effects-tutorial">Mocha tracking</a> to lock it in place</li>
<li>Add a glow effect to make them pop</li>
</ul>
<p>This technique makes the eyes look alive and dynamic, rather than just color overlays.</p>
<h3>Step 3: Creating a Ground-Smashing Impact</h3>
<p>This is where things get destructive. When Red Hulk smashes the ground, you'll need:</p>
<ul>
<li>Ground cracks</li>
<li>Burning steel wool effects to simulate fire spreading (<a href="https://actionvfx.com/redeem">redeem for free</a> with code &quot;HULK&quot;)</li>
<li>Steam and <a href="https://www.actionvfx.com/collections/free-dust-wave-stock-footage">dust waves</a> help sell the impact</li>
</ul>
<p>To make it work seamlessly:</p>
<ul>
<li>Track the ground plane so the cracks match the perspective</li>
<li>Use <a href="https://www.actionvfx.com/blog/how-blending-modes-work-in-after-effects">blending modes</a> like Overlay or Screen to integrate the effects</li>
<li>Add motion blur to enhance realism</li>
<li>Keyframe opacity changes so the fire and smoke evolve naturally over time</li>
</ul>
<h3>Bringing It All Together</h3>
<p>With these elements in place, you can refine the scene by:</p>
<ul>
<li>Layering <a href="https://www.actionvfx.com/collections/atmosphere/category">atmospheric effects</a> like embers, sparks, and dust</li>
<li>Adding subtle <a href="https://www.actionvfx.com/collections/free-camera-shake-presets-stock-footage">camera shake</a> for extra impact</li>
<li>Fine-tuning depth of field to make everything feel cinematic</li>
</ul>

<p>Well the good news for VFX artists is that you don't need a pilot's license to make a <em>Top Gun</em> quality movie. In fact, all you really need is <a href="https://www.actionvfx.com/blog/a-comprehensive-guide-to-the-best-3d-vfx-software">good 3D and compositing software</a> and an <a href="https://actionvfx.com/pricing">ActionVFX subscription</a>.</p>
<p>I recreated a scene from <em>Top Gun: Maverick</em> spending only 10 credits (<strong><a href="https://actionvfx.com/pricing">$69.30 during Black Friday!</a></strong>) at ActionVFX. No, it's not quite <em>Top Gun</em> quality (I threw it together in less than a week), but you get a pretty good idea of what's possible with high-quality VFX assets.</p>

How to Create a Nuclear Explosion in Blender with VDBs

<p>Selecting the right <a href="https://actionvfx.com/3d">3D assets for your VFX project</a> is crucial for creating realistic and immersive experiences. Whether you're working on a film, video game, or architectural visualization, the quality and technical specifications of your chosen assets can make or break your project. This comprehensive technical checklist guides you through the process of choosing the best 3D assets for your needs.</p>
<h2>The Significance of 3D Assets in VFX and Animation</h2>
<p>The 3D assets you choose directly impact the viewer's experience and the effectiveness of your storytelling. Poorly made or incompatible assets can lead to visual inconsistencies, performance issues, and a subpar end result.</p>
<h2>Key Factors to Consider When Selecting 3D Assets</h2>
<p>When choosing 3D assets for your project, there are several critical factors to keep in mind:</p>
<h3>1. Compatibility with Your Software and Pipeline</h3>
<p>Ensure that the assets you select are compatible with your <a href="https://www.actionvfx.com/blog/a-comprehensive-guide-to-the-best-3d-vfx-software">preferred 3D software</a>, game engine, or rendering pipeline. Check the file formats, versions, and any specific requirements to avoid compatibility issues down the line. For example, if you're using Autodesk Maya, make sure the assets are available in .ma or .mb file formats or are provided in a universally compatible file format such as FBX or OBJ. Assets that seamlessly integrate into your existing workflow will save you time and minimize technical headaches.</p>
<h3>2. Polygon Count and Level of Detail (LOD)</h3>
<p>Consider the polygon count and <a href="https://www.actionvfx.com/blog/what-are-3d-assets-learn-more-about-3d-models-alembics-vdbs-and-more">Level of Detail (LOD)</a> of assets in relation to your project's requirements and target platform. Higher polygon counts result in more detailed assets but can also significantly impact performance, particularly in real-time applications like video games. It is crucial to find the right balance between visual fidelity and optimization to ensure smooth rendering and real-time performance.</p>
<p>Many 3D models, <a href="https://actionvfx.com/3d">such as those from ActionVFX</a>, come with multiple predefined LODs. If the model is further away from the camera, a lower LOD can be used. This setup helps manage rendering resources effectively, especially in complex scenes.</p>
<h3>3. Texturing and Materials</h3>
<p>Pay close attention to the <a href="https://www.actionvfx.com/blog/how-to-import-3d-models-with-udim-textures">texturing</a> and materials of the assets. High-quality textures with appropriate resolution and detail enhance the realism and visual appeal of your scenes. Look for assets with well-crafted PBR textures (Physically Based Rendering textures) that accurately represent the intended materials and surfaces.</p>
<p>For example, a realistic metal surface should have a properly authored specular map that reflects light accurately, while a character's skin should have subsurface scattering properties for a lifelike appearance. Notice the reflection properties in this still-frame shot of an <a href="https://www.actionvfx.com/3d/mig-29-fulcrum-fighter-jet-3d-model">MiG-29 Fulcrum Fighter Jet model</a>, for example.
<img src="https://a-us.storyblok.com/f/1002378/800x450/4310554b52/mig_29_fulcrum_fighter_jet_3d-model.jpg" alt=""></p>
<h3>4. Rigging and Animation</h3>
<p>If your project involves character animation, evaluate the rigging and animation setup of the character models. A well-rigged asset with properly named and organized hierarchy allows for easier animation and integration into your pipeline. Consider the flexibility and compatibility of the rigging system with your animation tools and techniques. For instance, if you're using a specific animation plugin or workflow, ensure that the character rig is compatible and can be easily manipulated within your pipeline.</p>
<h2>Understanding the Technical Aspects of 3D Assets</h2>
<p>Understanding the technical aspects of 3D assets is essential for making informed decisions during the selection process.</p>
<h3>1. Topology and Edge Flow</h3>
<p>Analyze the topology and edge flow of the assets, particularly for character models and organic shapes. A clean and optimized topology with evenly distributed polygons and logical edge loops facilitates smoother deformations, animation, and texturing. Well-constructed assets with proper topology reduce artifacts and ensure better performance.

<h3>2. UV Mapping and Texture Density</h3>
<p>Examine the <a href="https://www.g2.com/articles/uv-mapping">UV mapping</a> and texture density of the assets. Properly laid out UV maps ensure accurate texture placement and minimize distortion. Consider the texture resolution and density in relation to your project's requirements. Higher resolution textures offer more detail but impact memory usage and loading times. Strike a balance that maintains visual fidelity while optimizing performance.</p>
<h3>3. Shading and Rendering</h3>
<p>Evaluate the shading and rendering settings of the assets. Look for assets that <a href="https://www.actionvfx.com/blog/mastering-your-3d-assets-essential-tutorials-shaders-and-resources">include appropriate shaders</a>, materials, and rendering parameters compatible with your rendering engine. Consider factors such as shader complexity, light interactions, and transparency to ensure the assets integrate seamlessly into your rendering pipeline and produce the desired visual results. If you're using a physically-based rendering (PBR) workflow, for example, make sure the assets include PBR-compatible textures that are compatible with your render engine.</p>

<h2>Selecting the Right 3D Assets</h2>
<p>Now that you understand the technical considerations, let's walk through the process of selecting 3D assets step by step.</p>
<h3>1. Define Your Project Requirements</h3>
<p>Begin by clearly defining your project's requirements and objectives. Determine the specific types of assets you need, such as characters, environments, props, or visual effects elements. Consider the art style, level of detail, and intended use of the assets within your project.</p>
<h3>2. Research and Evaluate Asset Libraries</h3>
<p>Explore reputable asset libraries and marketplaces, such as the <a href="https://actionvfx.com/3d">ActionVFX 3D Library</a>, to find a wide range of high-quality assets. Take advantage of search filters, categories, and tags to narrow down your options based on your project's needs. Read asset descriptions, view sample renders, and watch demonstration videos to assess the quality and suitability of the assets. Take the time to assess the asset's polygon count, texture resolution, materials, and overall visual fidelity to ensure it aligns with your project's requirements and quality standards.</p>
<h3>3. Test and Integrate Assets</h3>
<p>Before finalizing your selection, it can be helpful to test the assets within your project's context. Download <a href="https://www.actionvfx.com/3d/9mm-bullets">sample files</a> or purchase individual assets to evaluate their performance, visual quality, and compatibility with your pipeline. Integrate the assets into your scenes and assess how they interact with other elements, such as lighting, shading, and animation.</p>
<h3>4. Optimize and Iterate</h3>
<p>Once you've selected and integrated the assets, optimize them for your specific project requirements. Adjust texture resolutions, and shading settings to strike the right balance between visual fidelity and performance. Iterate and refine the assets as needed to ensure they seamlessly blend with your project's overall aesthetic and technical constraints.</p>
<h2>Invest in the Right 3D Assets</h2>
<p>Remember, investing in high-quality assets from <a href="https://actionvfx.com/3d">trusted sources like the ActionVFX 3D Library</a> can save you time, effort, and resources in the long run. Depending on your needs, it may be worth purchasing a higher-quality, flexible asset that can be used in several projects over investing in a low-quality 3D model that will only serve a single project.

<li>Use Mocha (free version) to track the eye movement, creating an elliptical mask around the cornea.</li>
</ul>
<p><strong>2. Adjust Mask and Track:</strong></p>
<ul>
<li>Refine the mask in Mocha to fit the cornea and prevent drift during tracking.</li>
</ul>
<p><strong>3. Apply the Eye Texture:</strong></p>
<ul>
<li>Import an <a href="https://www.actionvfx.com/collections/eye-textures-stock-footage">ActionVFX Eye Texture</a>, scale it down, and convert it to a 3D layer.</li>
<li>Position it over the tracked eye and feather the edges for a natural blend.</li>
</ul>
<p><strong>4. Color Correction:</strong></p>
<ul>
<li>Use Hue/Saturation and Levels to match the eye texture's color and contrast with the footage.</li>
</ul>
<p><strong>5. Add Reflection:</strong></p>
<ul>
<li>Create a reflection using a panoramic image with the CC Sphere effect.</li>
<li>Adjust the reflection's intensity and blend it using the Screen mode.</li>
</ul>
<p><strong>6. Composite and Add Shadows:</strong></p>
<ul>
<li>Use a track matte to blend the eye texture and reflection within the eye socket.</li>
<li>Add shadows with a feathered mask to enhance depth.</li>
</ul>
<p><strong>7. Final Refinements:</strong></p>
<ul>
<li>Pre-compose the eye texture for easy updates.</li>
<li>For a second eye, repeat the process with a different tracking point.</li>
</ul>
