When compiling character collision, tool tells me there are about 10 open edges. When i import debug.wrl it shows errors around faces on the character's knee. The thing is, these edges are closed.
Do collisions errors (open edges) have anything to do with skinning/weighted verts?

Make sure u don't have 2 verts in the same place.

Yeah, I welded everything. Plus, I can check by moving the verts around.
Update: It's happening again on the torso.
