turn out I was renaming j_gun to tag_gun instead of tag_weapon.
when inside maya before you binded the model itself the joints had the proper tags right ? like the clip was marked as tag_clip and so on?
I set my grid size very small and try my best to mimic the geometry in the original game. I have Black Ops 1 running on my other monitor while using radiant so that helps a lot. There's a lot of trial and error but I figure eventually I might port over some models from Moon using Maya and Lime, but as they seem very low quality I'd rather make as many with brushes as I can so I don't have to spend so long re-texturing.
