Anisotropy doesn't work with UDIMS

Has I have time for the first time of my life on a project, I enjoy it to communicate to you another issue.

I love to use anisotropy on some materials because it brings somthing more.

But few time ago, I discovered that it doesn't spread along different Udims.

Here is the exemple :

It reminds me of this issue, yet the seams became visible though displacement in this case: https://answers.arnoldrenderer.com/questions/17977/c4dtoa-displacement-seam-problem.html

Here's an article, which uses the utility shader connected to Anisotropy tangent (under the Geometry section) to overcome the problem: https://cgrenderdna.blogspot.com/2018/06/arnold-render-anisotropy-tangent-fix-uv.html

You can give it a try to see if it solves your issue.

That works !

Thanks Peter :-)

It just changes the aniso aspect a bit, but no a big deal.
