Render Material Turns BLACK

I am running into a problem with my current render. This is an aerial perspective (see image). The project has a lot of tempered glass. The glass is broken up into individual panes, and I am noticing that certain panes render as solid black while the adjacent panes render fine. I’m not sure why this is happening or how to fix the problem. Have you seen this before? Please advice.

Hi Matthew - is the object a mesh? What does Check say about it? You might try UnifymeshNormals or RebuildMesh and see how that does.

It is a mesh actually. I will try your advice. Thank you.

You are exactly right. Every one of those black panes has naked edges. Is there a way to fix them all at once?

Hi Matthew - can you send the file to to my attention? Please include a link back here in your comments.


Hey Pascal

Thanks for your reply. I just remade them. Thanks so much for your help.
