Have run into a strange problem.. and I just cant get it right.. I wanna put a bump onto a button made in wings.. Its just a square and the only bump on the modell so I dont Uv map anything just makes a squarish bump map that should fit.. I choose the bump and set bump to 100.. works fine in the lab with a vube and everything but when I go back to the real set nothing happens.. have never run into this problem before.. anybody knows how to get this working?
