Create a Maya model from a maya model
It might sound crazy but is it possible to make a retopology scan of a bad maya model using any known software? This is required in order to essentially correct bad GEO by rescanning and applying good build logic. Existing packages like mudbox assume a sound GEO so that won't work. For example, if I was to scan using a 3D package this would work but it assumes a real physical piece of geo, not one stored in 0 and 1's.
