What Sebastian said plus you can deform the wing membrane by a
non-double sided, rigged wing geometry using the various ICE Cage
deformers out there as well. We did this on Walking With Dinosaurs
quite a bit.

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

When modeling a thin object like a bat or pterosaur wing, what is
considered the best approach to avoid interpenetration when
rigged? I am cleaning up a purchased model and the wing has no
thickness. I'm sure this will hold up ok on screen but wondering
what an experienced modeler would do? Mudbox seems to hate how
this model is put together and I'm about to add the other wing
side in. My only reserve is that when rigged, we may have issues
keeping the front and back from penetrating.
I'd love to hear what some practiced riggers and animators think.
Thanks,
