So in Maya, I've made some edits to the MG08/15 to remove some of the textures and whatnot, I'm trying to make it look less "Steampunk" and more like the actual weapon. However, after porting it through asset manager, when I try to view it in asset viewer, the app immediately crashes. And of course, when I try to load up the game, that crashes as well. What am I doing wrong?

the model is too detailed, waw cant handle it, or it didnt convert right but if that then i dont think it shows up at all
