Perro
Key rules
Custom material files implement shade_material.
Optional shade_vertex can modify output before wrapper entry points.
Use custom_f_param/custom_v_param to read packed custom params.
Post shaders implement post_process(uv, color, depth).

WGSL Shaders
Perro composes custom WGSL files with engine prelude and wrapper entry points for materials and post effects.
Example
fn shade_material(in: FragmentInput) -> vec4<f32> { let glow = custom_f_param(in, 0u).x; let tint = custom_f_param(in, 1u); return vec4<f32>(in.color.rgb * tint.rgb + glow, in.color.a);}Related Resource Docs
