Inconsistency with vertex movement.ok i made a script that will find the first and last vert of a cube using the vertex color as marker. as far as i can tell my script should work with out a problem but when running test i find that sometimes it does not move the verts and does nothing and other times it moves part of the mesh. just duplicate the cubes a few more times and combined the mesh play with it a bit u will see what i am talking about. any help would be Appreciated.
