thx dave. Unfortunately its not working. I tried it on a cylinder. I made a Cylindrical mapping to all the object. Like it has texture everywhere. good. Then I want to add some bump to the sidewall. But only to the sidewall so i made a planar X mapping. Booth does not work. i can separate my object to have texture on parts & bump on the other parts. I need texture everywhere & bump on some faces & the 2 uve looks completly different. Where am i going wrong?
