Actually, there IS a drawback in my code. As the weapon model is rendered
AFTER triapi (or with depthfunc disabled), it shows in front of the
polygons. I tried to get a viewmodel pointer clientside and set its
renderamount to 0, but that did not work. I got it to be halfway
transparent, but it never disappeared completely. So what you have to do is
to set the viewmodel to NULL either serverside or clientside (the first way
definitely works - I haven't tried the second yet).
