Anisotropy Parameters provide control over the directionality of specular highlights. For some materials, for example brushed metals, the specular highlights are broader in one direction than another.

| • | Amount – Controls the amount of anisotropy on the material. A value of 0.0 means that the highlight shape is uniform; a value of 0.5 will stretch the highlight in one direction |
| • | Anisotropic Rotation – Determines the orientation of the anisotropic highlight. The base orientation is determined by the UVs of the mesh and this control allows you to rotate it interactively. |
