ShaderToy

Use this skill for ShaderToy-native work and ShaderToy-to-runtime migration.

This skill is narrower than shader. If the problem is fundamentally about ShaderToy built-ins, mainImage, channels, buffers, or porting out of ShaderToy, use this one first.

Workflow

1. Confirm the ShaderToy shape

Resolve these first:

• single Image pass or multi-pass with Buffer A/B/C/D
• uses of iTime, iResolution, iMouse
• channel usage: iChannel0..3
• whether the code is pure procedural or samples textures / buffers

If the user posts ShaderToy code, keep the original structure visible until the effect works.
