Enumeration Case

MDLMaterialSemantic.anisotropic

The degree to which specular highlights elongate in the direction of the local tangent basis.

Declaration

case anisotropic = 7

Discussion

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 anisotropic and map_anisotropic attributes when importing from the MTL file format (for assets in the OBJ file format).
