Probably not; it will become a problem though for meshes with a different inside
texture, some optimizations for artifact suppression (if there are, or ever
might be, such things) might fail to kick in, and I'd expect it to have the
potential of messing up one's bump maps, so it's generally a good idea to keep
one's eyes peeled for such issues.
