I fixed it, that's something with the *.qc files. Now i have new problem. My lasgun model is working, textures etc. etc. but it's shifted in first person view to back. I see only barrel... How to repair it? I really need fast answer. (i don't want start new topic)
@EDIT
I found what's wrong. The model is moved too much to back. I tried much times shifting it forward, but ALLWAYS MilkShape ignore it when exporting...
