Automatically flip only wrong normals ?

Silverland — Thu, 30 Nov 2017 19:43:56 GMT

I have a stadium 3d object with many thousands of sits. Some sits ( maybe 400 hundred of them) have reversed normals. How to flip normals only on this sits?

I would recommend Mesh Display>conform normals but it may not work depending how it was modeled, you can read more in the docs.

My advice is not to worry too much, it should render okay, do a test render.....and yes, if possible it would always be safe with completely clean geometry.

Give it a try.

You could also try to combine 400 plus seats with bad normals and flip them....maybe start with 100 objects, it might be too much calculation on 400 at once.

Hello! I need also to reverse the faces because I will import the model in Unity and there the revers faces/normals are transparent. Any plugin known that might help? Thank you
