2D Lighting Bug: Any light source defaults everything to be lit

I'm not sure when this happened, and I tried going back to other versions of Unity, but couldn't pinpoint anything, but perhaps someone knows something about this bug. Here's what's happening in my project now:

Say I have a project with sprites on two different sorting layers. I create a global light with intensity 1, but it's only targeting one of the two layers. BOTH layers will now be lit as if by a 1 intensity global light. Now if I reduce the intensity, the correct sorting layer sprite will have it's lighting reduced appropriately, but the other one, which the light should not even be affecting, will stay as if lit by a 1 intensity global light. If I drop it to 0, and then toggle the game object's active state, that is the only way I can get it to stop lighting layers it's not targeting.

tldr; The presence of ANY 2D light causes unlit sprites to appear as if lit by a 1 intensity global light. This bug persists in edit and runtime. Any help with debugging what might be the source of this would be appreciated.

 

Hey, did you fix this problem? I have the exact same thing. Any advice on this would be appreciated!

 

I haven't found a fix, I've just worked around it.

 

What was your workaround? I'm having this issue

 

Create point light for every sorting layer and make the radius super high so it always affects every object or just parent it to your player and just set intensity to 0. It works for me

 

Seems like he's not gonna reply. I will file a bug report on this. I have the same issue and it would be nice if you fix it

 

Never mind, I have another bug. The "Report a Bug..." window won't open and I can't find it in the installation folder either. I guess I'll have to report this bug first. Wait... What exactly should I do now?

 

Sorry any time I've tried to report a bug with the bug reporter that pops up I run into a world of hurt (maybe project size or something). I might have had a sample project that shows this bug but I don't anymore.

 

Experiencing the same thing. Is there a fix already?

 

Found a fix for this. You need to have a global light in ur scene that affects all sorting layers before adding other lights. If there's no global light, I think unity will automatically create one for u with an intensity of 1. But I don't think unity supports using multiple global lights each affecting different layers.

 

Yeah, that's pretty easy to reproduce:



Unity 2020.3.26f1, URP 10.8.1

 

I wondered why I hadn't seen this bug before, but we're using a system where we automatically spawn a global light targeting all layers both in edit mode and play mode, so that prevents it
