Faceted anisotropy when using uvw mapping

Hello! everybody!
I have a problem with anisotropy in materials.
When I make anisotropy, in my model appear edges?
PtintScreen of problem: http://clip2net.com/s/3NLWvI2

bad link?

Not getting anything from that link - can just upload the image direct to the forum, easier than using an external link of any sort :smiley:

Dead link, but maybe it’s about this?

Sorry, but I can’t add image to the forum :frowning:
Maybe, this link will be work: https://yadi.sk/i/_yfJpziC3MvEwy

Nobody didn’t have this problem?

The problem is UVW in material.

Issue when using anisotropy and uvw mapping. Not sure if unexpected.
