Back Face problem – Back Face Culling

 














When you use a model that comes from other software, (mainly SKETCHUP) sometimes there are many back face problems. 3ds Max has render option to “Force 2-Sided” and when it is on it renders both sides of the face, which normally isn’t a big deal. However, if you use a mental ray and Arch & Design template material, sometimes the option doesn’t work.











Because some templates default turn on “Back Face Culling”. You just need to turn off this option and it will render back face again. Back Face Culling is under the Advanced Rendering Option.
I used Satin Varnished Wood Template.

If you don’t get a smooth surface, select entire model using Polygon selection and hit an Auto Smooth.
