hi....all .....iam eng.tamer bader from jordan ....i am realy overwhelmed about this wonderful site .
i just wanna say something about the nurb problem :
source : a specialized book in 3ds max5
follow these steps
1- right click on the top left of the 3ds max screen ....configure ...force 2 sided
2- rendering parameters f10 : nurbs is working very well with (active shade)
and don't forget to check (force 2 sided ) too . then render
3- use multi sub object all the time ...in conjunction with nurbs modelling ( just if u wanna assign materials )
those 3 streps are extremely improtant ...
