Effects

Pick the Engine building block first, then adapt its closest official example with find-examples:

• Particle systems: the particlesystem component (graphics/particles-* examples).
• Custom shading on existing surfaces: StandardMaterial chunk overrides (override-shader-chunks), or a ShaderMaterial when the effect needs its own shader pair.
• Procedural or per-frame geometry: a runtime-updated Mesh on a render component (graphics/mesh-* examples), or WideLineRenderer for lines with width.
• Full-screen effects: CameraFrame (light-scene).
• Gaussian splat effects: the shipped gsplat scripts (reuse-scripts).
