anisotropic shader problem

[sean_G]

yup sorry to be the one to break it to you , but the anisotropic shader only works with NURBS objects because only NURBs objects have inherent UV co-ordinates, which are required to calculate the deformation of anisotropic specular.
theres not really a fix, but there is sort of a workaround. you can reduce youre specular to a infintessemly small number, like .001
or .01 , and blur it. though this often produce undesirable results. or negate the anisotrpic specular all together
and use another shader for specular and pump them both through a mix node.....

tdmack,

I know you already received this answer (at XSI Base), but this is for anyone not visting XSI Base.

How to use the anistropic shader on polygon meshs:

Plug a integer share node into the surfderiv_mode input of the anisotropic shader. A value of 3 provides nice results. Not entirely perfect compared to using the shader on nurbs but its works in most situtations.

thats a great fix.. i never saw that article in xsibase. thanks.
