I imported this obj part made in Rhino. I can’t add or subtract material on the sides of this part? You will see that they are un-effected when I try to add/subtract or smooth them out. When I try to smooth them they take on a dark shattered look. I can work with the top surface and bottom but not the sides? Why? Anybody know why? It’s comming in at a 130000 polygon count.
