I have imported a file from a CAD system and unfortunately it has on nearly (not all) every polygon a second one with a reversed normal. When I render it I get these Z-buffer related glitches. I tried to combine them and merged vertices with a small value but had no luck.
Can anybody help me with selecting and removing these superflues polygons?
I think it is pretty easy... but don't know how to do that! *arrgh*
Thanks!
Holger
