anisotropic in blender/yafray

hi

anybody knows if yafray supports anisotropic shader for rendering brushed metals in blender?

claas

I don’t know if Yafray can . . .

But, I’ve had reasonable success in the past in using a procedural wood texture as a bumpmap, scaled really small (ie set the material texture scaling to >20) and subtle, which in certain cases has worked well.

My understanding is that true anisotropic shading requires calculation of a tangent, as well as a normal, and whilst reasonably easy to get off a NURBs patch model (which is how I think most of Maya, for example, does it) I wouldn’t know where to start with just polys.
