Both .maxc and .vue file come from 3ds max, so if any kind of maxc to vue conversion is actually possible, it would be done with this software. We have found no mentions about this export though, so either it is something done in previous versions of the software or for some very specific reason. You can always reach out to Autodesk support or 3ds Max online community for help as this might be the only way to help you achieve this kind of export.
