but you have to have that collect of those functions in an include file
no I usually just add a few commands at the top of the bmx file i'm working on if I find a missing function.
I've had to supply some constants for arb type calls, (and maybe a routine from memory) but not really come across anything max cant handle...
I've even overridden standard opengl calls to log them and then call the opengl routine, which is interesting but slow!
I'd be *really* suprised if you were to find something in opengl that you couldnt do in max
