MDLMaterialSemantic.anisotropicRotation
The angle at which anisotropic effects are rotated relative to the local tangent basis.
Declaration
case anisotropicRotationDiscussion
Values for this semantic in the range from 0.0 to 1.0 map to angles from 0.0 to 2 * M_PI. This semantic has no effect in a mesh that does not contain vertex attribute data providing a tangent basis.
Model I/O uses this semantic for the anisotropicRotation and map_anisotropicRotation attributes when importing from the MTL file format (for assets in the OBJ file format).
