Gary,
<<By different effects do you mean faces that were darker or brighter than they
were in different columns?>>
Some faces had the appearance of having been punched with a square nibbler
others were unaffected. I am trying to be more consistent when I draw the 3d
faces to go counter clockwise. I have not tried pfaces. I would guess this
might be a headache for 3D Studio but then again it might be better than plain
3dfaces!
Thanks for your advice,
Bill
