Unify Inward/Outward Primitive Normals

Recommended Posts

Before I go ahead and try an overcomplicated approach using raycasting I thought I'd check to see if anyone here has a simple solution to this problem.

 

I have a model from maya, that has had many sections mirrored, thus creating sections with primitive normals facing inward rather than outward.

Is there a simple method of making all normals face outward?

All of the poly shells are enclosed as well, so no open surfaces to worry about.

Well, here's the raycasting method.

 

It works perfectly, on enclosed (or at least mostly enclosed) poly shells.

 

It won't fix individual faces with incorrect winding though, only whole shells.
