Hi, I’m quite new to unity so I’m not familiar with some aspects of its utilities or tools, but when it comes to lighting I’ve come across with this issue (see embedded video clip), also in this scene I deleted the directional light to see how dark or bright my lights are, even if I bring the directional light back the issue is still happening.
On your ceiling, are there multiple objects overlapping? Could also be related to the priority of your point lights. The defaults in forward rendering basically will show those point lights closest to the player. You can try setting the point lights to “always on”.
Also, consider using deferred rendering if you have lots of realtime point lights.
Did you try deferred rendering? I’m pretty confident that it’s one of things I already listed that’s causing it. Your objects can’t overlap at all. It could be z-fighting on your models.
What are your plans for using unity? Are you trying to build a game? I’m asking because this probably one of the easier things you will encounter. If I had the project open on my end I could find it pretty fast. I don’t want to discourage you, but troubleshooting this (with or without help) is one of the easier things you’re going to experience depending on what you’re working on.
