I’m currently working on a weapon model hack (in other words, pasting a gun on a different set of animations) with 3DS Max, and everything looked great until I went to preview the anims.
Et voila, screwed UV maps.
The original gun on its original anims is perfect, but not the new compile. I’m not sure if, or even how the previous gun’s UV maps might still be there?
That’s the only thing I can think of. By the way, the original and replacement are right-handed in model viewer but left-handed in game. Not sure what’s going on there, either. And yes, it’s the only weapon with that issue.
