Shader bits for the WebGL (GLSL) backend

Shader bits for the WebGPU (WGSL) backend

Whether the compiler adds the camera's position and matrices in the camera bind group

Set it to match the template: false for one with no camera group. The compile throws when they disagree. A material's descriptor ignores it and always has them.

Whether the compiler adds the view-wide values, such as the lights and fog, in the global bind group

Set false for a template with no global group, or when the bits declare a global group of their own. A material's descriptor ignores it and always has them.

Which of the bits' ShaderBit#outputs each location writes, by name: entry n is location n, the target's colour attachment n

An output left out never reaches the GPU, and a name no bit declares leaves its attachment alone. A material's descriptor ignores it, since the engine sets a material shader's locations. Each distinct list compiles its own shader. A template without the output slots ignores it.

Values for the bits' specialization constants (ShaderOverrideDef), such as { OUTLINE_WIDTH: 0.1 }

Each distinct set of values compiles its own shader.

Custom shader template

Left out, a material's descriptor uses the engine's material template. A pass's descriptor has no default and must set one.
