I am trying to do something that was simple in Oblivion but seemingly impossible in Morrowind. I downloaded a companion mod called Companion Wolf spot 3.0. All I wanted to do was change the wolf nif file into a different creature of my choosing (winged twilight) and rename it. But for some reason after choosing the new nif, the animations are lost and I can't figure out how to reload the animations for the default creature. The game crashes and it says no animations found. How do I set the new animations for the creature after I change the Nif graphic model? I don't want to change any animations or anything I just want to use the original ones, but the Animation box is grayed out and I can't choose any (kf files?). I already extracted my Bsa files from Morrowind but I still couldn't do add any animations. I'm hoping eventually to add my own dialogue too but right now I am wondering if it's even possible to do what I want. I don't understand scripting and I do not know how to program them at all so I have a huge disadvantage.
Would appreciate any help please, I have read for hours on other sites from searching Google but I can't really find any solid info.
