ludus::content::scene_format::MaterialRecordV6¶

Struct

Version 6 material: version 5 terms plus texture-modulated surface detail. SurfaceTexture is linear data, never colour: RG encode the tangent-space normal XY as 2 * channel - 1 (positive Z reconstructed, +Y along the vertex bitangent cross(Normal, Tangent.xyz) * Tangent.w), B multiplies Roughness (floored at MIN_ROUGHNESS) and A multiplies Metallic. EmissionTexture is sRGB colour whose RGB multiplies Emission. Both share Texture's coordinates and address mode. A texture referenced as a surface map must not also be a base or emission texture.
