Lights showing on ceiling in different room

The lights on the edges of the ceiling are coming from different rooms. The ceiling for each room is a separate object and connect with the walls, so I don’t understand how they’re bleeding through.

Can anyone suggest what to check?

Thanks

Are these all realtime lights with shadows enabled, or are you baking anything? Also, are there any reflection probes in the scene?

Yes, all realtime with shadows.

I have not added any reflection probes.

Thanks

Which render pipeline is this? And how many lights do you have? I’m wondering if you are hitting a limit on the amount of shadowmaps

This is HDRP. I’ve counted 32 realtime lights.

Thanks

If disable every light except a single one, one the problematic ones, does the issue still reproduce?

Yes, here is the scene with only one light enabled (on the other side of the door) and it is still bleeding through

Hm. This looks like a bug to me, as if the shadowmap isn’t being applied to the specular contribution from the light. I’d suggest filing a bug report.
