Pick the Engine building block first, then adapt its closest official example with
find-examples:
particlesystem component (graphics/particles-* examples).StandardMaterial chunk overrides
(override-shader-chunks), or a ShaderMaterial when the effect needs its own shader pair.Mesh on a render component
(graphics/mesh-* examples), or WideLineRenderer for lines with width.CameraFrame (light-scene).reuse-scripts).CurveSet takes one key array per channel. A flattened array type-checks, then fails at texture
upload.reset() then play();
one-shots use loop: false.setParameter, not a per-frame material.update().Trigger each effect through the app's real inputs, and confirm repeated triggers keep entity counts stable.
