LeMi - Fire Spread

Lemi – Fire Spread is a high–performance fire propagation package designed specifically for Unity’s Universal Render Pipeline (URP). Using Compute Shaders for GPU acceleration and VFX Graph for visually rich flame effects, this system brings dynamic fire simulation into your scene. The shader included is highly customizable — adjust noise layers, blending, curvature and depth to create entirely unique flame styles. While the system focuses on visual fire spread and does not include grass interaction, it seamlessly complements terrain and foliage workflows, making it ideal for action, survival, open-world or simulation games that feature dynamic environments.

Details

• GPU-accelerated fire spread via Compute Shader
• VFX Graph integration for realistic flame visuals
• Highly customizable Fire Shader: BaseMap transition + dual noise layers for varied fire styles
• Parameters: Power (blend strength), Distance (depth/curvature), Offset (view‐direction bias)
• Terrain alignment: particle effects align to terrain height
• Collision detection: trigger events when objects enter/exit burning areas
• Designed for LeMi - Interactive Grass And Detail Generator, also can work independently
