[need help] model replacement: no textures

hello,

i'm currently working on a mod that will replace the mabari dog (party member) with a wolf model. while i got it to work through an APRbase change, the game won't apply the right texture. the dog basically looks like a golden statue (no/wrong textures?).

i also noticed, if i use the appearance cheat, the result is the same. if i use the appearance cheat on my hero, the wolf model looks fine.

any suggestions?
