Hello, i have made two weapons, a G36C assualt rifle With 3k Verts and a variation on the ump .45 submachine gun.
Why these are modders resource is becuase they are badly textured and UV mapped. I hate uv mapping and maybe ill do it sometime later.

EDIT: well before i exported the G36C it was about 3k, I imported it from its .nif form and its almost 8k! why is that?

It's because the 3k count is in quads, and when you export the mesh gets triangulated for the game engine, the quad count is the same (a quad is just two tris) so you effectively double your poly count on export.
