Yeah, I think you might be right, both of you. I had a lot of models that had this problem, and it seems that it is like some kind of virus, like if I use a model from the weapons cache it has the problem, or my body mesh, but if I make a model from scratch it works sometimes. I had a lot of models that were bad and good, and I have had the problem for months now... what caused me to procrastinate was my computer crash, and unfortunately I lost everything.
