In our latest tutorial, we break down practical techniques for compositing blood that actually feels grounded — whether it’s on walls, floors, props, or people. If you want your scene to hold up in motion and match the lighting and texture of the environment, these are the tricks you’ll need.

And yes — you’ll want to watch the full tutorial. But here are some key insights to get you started.

1. Choose The Right Assets

Not all blood elements are created equal. If you’re using static textures or low-res clips, your shot will always feel flat.

ActionVFX blood assets are high-resolution and constantly moving, which means they ripple, spread, and distort in realistic ways. Whether you’re using pools or sprays, this movement is key to selling the effect — especially in slow motion or high-action sequences.

Looking for maximum flexibility? Go for the EXR collections, which offer:

• Lighting passes for realistic integration

• Greater control over highlights and shadows

• Scale flexibility without losing quality

2. Use the Right Color Space

This might seem basic, but it’s often overlooked.

Each ActionVFX asset collection comes with a listed color space — make sure to match it inside your compositing software (Nuke, After Effects, Resolve, etc).

If you're in the wrong color space, your blood will either clip, crush, or look completely disconnected from the scene. Get this right early and save yourself the grade headaches later.

3. Match Practical with Digital

Whenever possible, try to add practical blood to your set — even just small amounts.

Why? Because matching your digital blood to real-world drips or stains helps anchor the effect. You’re no longer starting from a blank surface, you're blending, enhancing, and extending what's already there.

This makes your comp feel more like a clean extension than a bold insert.

4. Integrate Lighting, Not Just Color

Blood is reflective. It catches highlights. It shifts with ambient tone.

To push your realism, use lighting passes (available in EXR formats) or create your own with blend modes. Here’s how:

1. Duplicate your blood layer
2. Tint it with a soft red-orange glow
3. Add a wiggle expression to opacity
4. Set the blend mode to Add or Linear Dodge

This gives your blood subtle specularity that responds to the light source, making it feel like it’s really on the surface, not floating above it.

5. Break It Up — Avoid the “Sticker” Look

Too often, blood elements are just slapped onto a surface with no integration. To avoid that, try these:

• Use corner pinning to follow floor or wall angles
• Add subtle warp/deform effects for pooling behavior
• Mask edges with soft feathering and real-world grime
• Match grain and motion blur to your plate

Even better: use ActionVFX assets filmed from multiple angles, so you can pick the one that fits your shot’s perspective.
