For now there are three different mesh groups with 3 different skins + map with a standart model material assigned. Nothing special. I played arround with some shaders and assigned them via ent_mtlset. But whenever I did this, the whole model appereance changed. Some parts lost there alpha. Some parts where shaded in different colors. Only the skin set in ent_mtlset was not affected.

If I assign a shader to one skin via ent_mtlset, to which skin is entskin1 pointing?
