the first seems to be a Tigon Take a look:Tigons are not real new races, are shapeforms from some Troll Priests. But they are kool!:DI have them showing clothes ^^ Learning how to add them more .anim Maybe could u fix female shoulders?
Are the Tigons using the standard UV layout? Cause if they don't you'd have to reskin them/edit the UV layout which means editing the model, thus loosing all animation related information which would then have to be redone (too much work to bother with)
