Rendering turns curtin wall glass black, Help.

[jacob21]

I imported a file from Revit 2012 into 3ds Max Studio and every time i try to render it shows the curtin wall glass black, funny enough in the Environment/Effects dialog it shows it as clear.

 

What gives?

try flipping the faces of the glass, if that doesnt fix it, could you post a screenshot of your material?

[Fooch]

flip faces or shell it. (might be single face)

[Justin Hunt]

you also have your reflection/refraction turned OFF

How did you import it? In the past I would get artifacts that would come in as black from Revit. I could never fix the problem. I also get some UV mapping issues as well sometimes.

 

In the case of the black geometry, I could not map anything to it. It never changed no matter what I did. So, I just erased the geometry and fixed it in .Max. It is quite annoying.
