Hi there, I was thinking of buying the new version of Carrara but I was looking for an answer to a question first. Could someone tell me why the opening on the left is so rough (even when rendered)? This opening was made by deleting polygons then adding polygons around the inside thickness in the vertex modeller. The opening on the right was done using a Boolean operation and is much cleaner. Surely this cleaner look can be achieved by deleting polygons too - can it not? Cheers
