ludus::graphics::renderer::SceneShaderMaterial¶

Struct

Borrowed fixed-mip RGB reflection material. Scene graph Update copies all values and texture bytes before returning. Maps are RGBA8 unorm or sRGB color/emission; surface data is unorm RG normal, B roughness and A metallic. Omitted maps are white. Typed conductor evaluation uses constant Scattering alpha/Eta/K instead of the base colour and roughness/metallic multipliers; surface normals still apply. Layered coatings use the base colour for their diffuse substrate and keep the constant Scattering alpha/IOR/thickness; normal mapping still applies.
