I use Ray 3.4.
And I do not know the UVW parameter in Anisotropy. how it works?
Someone can help me please??

The UVW option allowed control of the highlight reflections directionality based on a texture map. When experimenting with this, keep in mind the results are more evident if the highlight glossiness value is slightly lowered.
We've redesigned this part of the interface in the v3.6 update. It is strongly recommended to download and install the latest v3.60.02. The update is free for v3.4 users.

Kind regards,
Peter
