Like for a totannly new mesh like askeleton or other stuff?

If you're an expert in at least one 3D modelling program like 3D Studio Max, and have a lot of time on your hands...I haven't looked into it myself, but I'm sure it's doable.

wel the skeleton pieces are already there , it could take really few to rig etc but there are tons of stuff to edit in CK that gets me lost , I tried to make a mannequin in stone , and failed couse it didnt appear ingame so I gived up ... actually I wanted to make animated statues with specific stone retextured armor ... so to look like moving statues but .....
