Super helpful video. Thank you!
Also, very strange. I’ve never seen this before, so this is what I’d like for you to do (unless someone else jumps in, having seen this before.)
- When you duplicate the door (mesh) does it have the same brightness?
- Does the door use the same material as all the other doors?
- Can you see the door when there is no light? (I ask, because it might be emitting light.)
