Texture on torus model?

I have a problem with my model and texture on it. I have a half torus model with some “stairs” on the surface and I need to setup the texture to rendering. The texture should be like by circles not in parallels… Here is a link for better knowing. Can somebody help me? Thanks!!

Hello - you’ll have to post the file, or at least export the part of it that you’re asking about, along with any textures that you’re using - if it cannot be not public, send to tech@mcneel.com
