Question A Surprisingly Miniscule Problem

Hi
I have a very peculiar issue in the latest Unity editor, there are various baked light solutions and workarounds of course, but Im scratching my head over the actual logical issue that is happening in my scene. Fully replicable with any type of light and tested across various different scenes with all kinds of different settings.

The issue is as simple as, on the 5th light I add to a scene the entire scene gets flooded with ambient light. There are screenshots attached that show this in an empty scene with only 1 box and 5 lights being created, the fifth extends way beyond it's defined range.

What am I doing wrong here?

1. Create light
2. Position light
3. Light behaviour does not follow basic physics....

 

Per pixel lights are limited to 4 by default in forward lighting. You can change in the settings I think if you are on URP, not sure if you can change it in Built in though.

 

The fifth light (in the screenshots) is forced to be a vertex light, so the lighting on wall looks to be wrong.

For URP, you can increase the maximum additional lights allowed to at most 8 in URP assets.

For Built-in RP, you can increase the maximum additional lights allowed in default (Forward) rendering path, but may lose lots of performance.

If you need more real-time lights, you can try switching to:

• Deferred rendering path (Built-in RP, URP 12+)
• Forward+ rendering path (URP 14+)

 

Yeah, that makes perfect sense, thanks. Just didn't realize the limit was set as low as 4. Much Appreciated.
