#DETACHING FACES

A very peculiar thing happened today. I detached a set of faces from an object that I was making and created a second object. Now I did not move this second object from its original position. However, after rendering again I can see the sides of the detached faces;they were not flush and seemless along with the rest of the main object. After reattaching the object and even remapping as one object the seams were still showing!! What is going on?? help!!!!

Stephen, I don't know the shape of your object, but it sounds like you might get this problem with different smoothing groups assigned to your faces. Does the geometry in question all share the same groups? Bob W.

Stephen, You see the seams because smoothing can only occur across welded faces. Even though you have attached the faces back to the object, they still represent a separate element within the object. You must weld the vertices where the faces share edges before they can be smoothed again. If you need to preserve the mapping that you have applied, you must weld one vertex at a time. Welding a group of vertices with a selection set will destroy the mapping coordinates. You can find a discussion on this in chapter 10 of Inside 3D Studio. Steven
