Question Anisotropic shading on Subdivs

Hello everybody :-)

First time poster and I already have a question...

I'm trying to create some good looking hair for a woman's head by using a lot of subdiv-grids (Fur didn't work in this case, mainly because the hair is quite long)
For the shading I tried to use the anisotropic one but it seems to be broken on any poly- and subdiv mesh while it works fine on nurbs. The meshes have an uv-texture but it still doesn't work. I'm using mainly XSI 2.02 but the same problem occurs in the orlean beta, too.

Is this a bug or am I doing something wrong ???

Does anyone know a solution for this, probably even some way to fake the anisotropic highlights?

Thanks in advance for any suggestions

Re: Anisotropic shading on Subdivs

It's not a bug, and you're not wrong. The anisotropic shader uses the native UV coordinates of a nurbs surface to orient its specular info. Simply put, it won't work on polys, even with explicit uvw projections.

Sorry I don't know how to fake it.

Salutations - Cheers
