oa::StandardSurfaceMaterial

Full Standard Surface PBR material. Parameterized on Autodesk Standard Surface / OpenPBR. Maps losslessly to glTF 2.0 pbrMetallicRoughness + KHR_materials_ior, KHR_materials_clearcoat, KHR_materials_sheen, and KHR_materials_subsurface_scattering. Arnold and Cycles standard_surface import is a natural correspondence. Texture channel packing (ORM convention): orm_texture R = ambient occlusion, G = roughness, B = metalness. normal_texture stores tangent-space XY as BC5 SNORM; Z is reconstructed as sqrt(saturate(1 - dot(n.xy, n.xy))). All color values are linear at this API boundary.
