Triangulated faces rendering issue with 3ds max nurbs

[juangala]

Hi guys,

Does anybody know what may be causing these triangulated faces on my renderings? It's just a simple npower nurbs made of 4 splines. No mapping, no materials. I am attaching the viewport image and one render with the annoying thing.

I am working with 3ds max 2011 and power nurbs.

Hi,

 

It seems that some faces are not correctly oriented. You can flip them manually.

 

It would be easier to apply a 2 sided standard material or an A&D Material with backface culling unticked.

Fast and easy, thanks!!

Do you know a way to avoid those triangles back faces, using any metallic paint material?

(kind of backface cooling)
