the wing thickness needs to match up, the verts on both sides need to match up, this way when weighted identically, the two sides of the thickness move in unison, this is easily done using the apply thickness ICE deformer, you could potentially just have that live, depending on your needs, however i don't think the out of the box ICE deformer respects uv's. i'd just freeze it, and weight it as such, an other threat of interpenetration might come from your topology being inadequate for the deformation you want to perform, mesh density can also be a big issue. if the topology is to sparse interpenetration will occur if the mesh is stresed.
so - make sure both sides match, as close as possible at a vertex level. - make sure your weighting is identical on both sides of the thickness - try and fix topology if it isn't clean - make sure your mesh is dense enough to support the kind of deformations you need. hope this helps. good luck On 1 July 2014 20:21, Byron Nash <[email protected]> wrote: > When modeling a thin object like a bat or pterosaur wing, what is > considered the best approach to avoid interpenetration when rigged?
