Renaming a URP Renderer asset to a name matching one of the Renderer Feature names causes erroneous behavior
If a URP Renderer asset has any Renderer Features assigned, renaming the Renderer asset to a name matching one of the Renderer Feature names causes erroneous behavior: the URP Renderer and the Renderer Feature switch places.
The following scenario shows how the error occurs:
- Let's assume that the URP Renderer in your project is called
ForwardRenderer
.
The Renderer has a Renderer Feature called NewRenderObjects
assigned.

Renaming ForwardRenderer
to NewRenderObjects
causes erroneous behavior:
The Renderer switches places with the Renderer Feature and does not behave correctly.
To avoid the issue, do not give the URP Renderer asset the same name as the Renderer Feature asset.

Warning about _AdditionalLights property when upgrading the URP package
In certain cases, you might see the following warning when upgrading the URP package to a newer version:
Property (_AdditionalLights<...>) exceeds previous array size (256 vs 16). Cap to previous size.
This warning does not cause issues with the project, the warning disappears if you restart the Editor.
