Remeshed avatars with skirts or dresses aren't properly remeshed
Not quite sure how to sum it up, but basically any character with a skirt or dress, when you remesh it in the avatar export, you end up with the item all messed up.
Here's a small example -- take this into Transformer, then export via the avatar and choose remesh and with ANY options there the skirt will end up all screwed up (and because we don't have physics on remeshed avatars there's no way to fix this in iClone).
