@PietroNifosi You could try exporting your model in FBX format (with smooth groups arranged the way you want them) & then do Atlas Mapping in MED, so that you get second skin UV map directly from the game file. Check out my shadowmapping example if you have time: http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=341024#Post341024
