View Full Version : Symmetrical Blendshapes...

08 August 2005, 04:32 AM
How do you get symmetrical blendshapes. If I'm doing a smile, I delete one half, then mirror geometry, and make it one piece again. When I load my smile shape in the blendshape editor, my face crumbles. What's going on?

The problem is when you do the delete, mirror, etc, you get different vertex orders and so on. The mesh may look similar, but the vertices have to be in the same order, with the same faces and edges and such for it to work. So once you copy the base geometry for doing a blend, don't alter it. It won't have the same internal topology.

There are a lot of tools out there to mirror shape changes without changing geometry. I like abSymMesh, but there are a few others out there. Check highEnd3D and you should find something that works for you.

Try Sym Work. Thats what I use. Also Mac ( has a bunch of tools and he also has a blendshape one. Also this guy ( has neet blendshape tricks.

Good luck.
