You dont have to know how to rig or weight, just how to extrude a part seperate it tweak it re-uv it and viola new model part.this trick should be taught in the hopes that instead of porting,its just as easy to make you own low poly jka ready version. easier actually. I mean like a base mesh already in .glm with non textured uvs a skin file and a tutorial on the process.people could make packs of things like backpacks helms, just heads, ready to frankenstein. I much prefer kitbashing than porting and chalknye your right to be annoyed by ported content and probably frankensteiners like me, you did the hard work that some people are to lazy to do or to dumb (me lol)
