Question URP Light2D working in Editor, not on Windows build

Hello,

On my project I add a simple Light2D Spot object. It displays correctly while running the project through Editor however as soon as I run the build, I get the error below and the world is not rendering.

I really think that I setup URP correctly for my project. Can someone help?

Thanks a lot!

Just ran into this issue myself, in my case it was caused by adding a Light2D via AddComponent, because the m_ApplyToSortingLayers field (shown as "Target Sorting Layers" in the inspector) is never set. Unity defaults it to "Everything" if the value is null on Awake, but only in the editor (https://github.com/Unity-Technologi...ipelines.universal/Runtime/2D/Light2D.cs#L489), which is why it breaks in the player.

I wasn't able to find a way to set the value normally during runtime, but I only looked into it for a few minutes so I may have overlooked something. Seems odd that there wouldn't be a way to do it though, given that the field seems to be required for the component to work at all, unless Unity doesn't want us using AddComponent to spawn lights during runtime. It's possible to set it via reflection but I'm not sure if that would potentially cause other problems, and I'd rather avoid using reflection to do it if possible. Hoping someone else has a proper solution for this.

For reference I'm currently using Unity 2022.3.10f1 and URP 14.0.8.

 

Thanks for reply! Just for records, I am using Unity 2022.3.7f1 & URP 14.0.8

 

Hey there,That error can be a real head-scratcher. It seems like your Light2D Spot object is causing issues in the build. First, double-check your Universal Render Pipeline (URP) settings in the build. Sometimes, settings don't carry over perfectly.Also, ensure you're using the correct URP version compatible with your Unity version. Mismatched versions can cause funky problems.Lastly, examine your build settings. Sometimes, specific platforms or build configurations can cause rendering hiccups.Debugging this might take a bit of trial and error, but you'll get there. Happy coding! ️‍♂️️

 

My latest build started throwing pretty much this exact error. It started right after I upgraded from 2021.3.24f1 to 2022.3.11f1.
When I run an earlier build built with the previous unity version 2021.3.24f1 the error doesn't happen.
I have URP14.0.9

EDIT: For me it was not with Using ADDcomponent, but something related to light layers and how they interact. When I set everything to only affect the Default layer the error didn't happen again, but I'm not sure what was the exact issue.
