Material Customization

🎨 Blood Designer’s material system gives you full creative control over the look and feel of your blood textures. It’s based on a highly modular Material Instance called MI_BloodDesigner, which you can tweak directly inside the editor.

By adjusting different parameters, you can create anything from subtle stains to large, detailed blood pools.

🛠 Main Sections

When you select the Designer material (inside BP_BloodDesigner), you'll see these key customization areas:

🧩 Base Settings

  • Base Texture: Choose the main base texture for your blood (optional).

  • UV Scaling: Adjust how much the base texture repeats across the plane.

  • Opacity: Control the overall transparency of the blood.

🩸 Layer 01 (Primary Layer)

Layer 01 forms the main body of your blood splatter.

You can control:

  • Noise Texture 🎨 Select a procedural noise to define the blood’s overall pattern.

  • Sphere Mask Texture 🧪 Adds a mask to create a more organic, radial falloff or custom edges.

  • Layer Intensity 🔥 Controls how strong/dark this layer appears.

  • UV Tiling 🧵 Scale the size of the noise texture independently.

  • Noise Detail & Distortion 🌊 Adjust how sharp or blurry the noise looks and add subtle warping for realism.

  • Layer Opacity 👻 Set how transparent this specific layer is compared to others.

🩸 Optional: Layer 02 (Secondary Layer)

Layer 02 gives you an additional blood pass if you want more complexity or color variation.

You can control:

  • Enable/Disable Layer 02 🔄

  • All the same settings as Layer 01 (Noise, Sphere Mask, UVs, Intensity, Opacity).

▶️ Pro Tip: Use Layer 02 with a different noise or color to add variation and realism without needing multiple decals.

🎯 Why Customize Layers?

✅ Add more detail to blood pools or large splashes. ✅ Blend different noise patterns for a more natural look. ✅ Create light vs. dark blood variations for story or scene differences. ✅ Achieve stylized, painterly, or gritty effects depending on your project.

⚡ Quick Workflow Tip

After tweaking material settings:

  • Always preview your blood on the black plane in the scene.

  • Minor tweaks to Noise UV or Intensity can dramatically change the blood's "feel"!

  • Keep "Layer 02" disabled if you only need quick, simple blood splats.
