Hey, thanks Dino,
some interesting points. However, I'm not a programmer, I'm more of a
"scripter" so all I'm familiar with is Python and MAXScript (native 3ds
Max scripting language).
I have no idea how to access the generic/non-generic engine, further
more, I have no idea what the difference is.
As for scope, I can do that, the problem is, I have no idea how exactly
to do that. Is there a documentation on this subject somewhere?
Thanks a lot for the tips, I appretiate it.
