So I started importing the five seven from bo2 into waw. I exported the models from models and everything and now ever since I exported the xmodel and xanim of it and tried putting it in waw, I go to play my map and I have no weapon or anything. None of the original anims fx or xmodels can be found and idk why its doing this.

you did it wrong. Re-watch the tutorial you followed and do it again

Alright. How would I get all the anims xmodels and fx (the waw ones) to work again?
