I thought that issue related to Additional Lights Cookie Format (GrayscaleHigh) on this line:

2025.02.14 19:42:16.024 17253 17585 Warn Unity Additional Lights Cookie Format (GrayscaleHigh) is not supported by the platform. Falling back to 32-bit format (RGBA8 UNorm)

However after i tried to change Additional Lights Cookie atlas format from ‘Greyscale(High)’ to ‘Color(Low)’ in all URP settings assets, warning messages about light cookie are gone but error still shows up:

Also, I also checked this post, thought that maybe it’s related, but it seems like there are already UNITY_ANDROID added in my Renderer script:

Unity 6 - Android Rendering Broken

@cmart1 I checked and the code change are in 6.0 and 6.1. I downloaded 6.1a9 (latest 6.1) from hub, created a 2d project and it has the code in there. I’m not sure why you’re still having the problem. Maybe delete Library, maybe the URP package didn’t update with the new code? In the project, if you open Packages/Universal RP/Runtime/2D/Renderer2D.cs, it should have #if UNITY_SWITCH || UNITY_EMBEDDED_LINUX || UNITY_QNX || UNITY_ANDROID on line 9.

Sorry but how is that a solution? It’s a very dirty solution

[HajiyevEl]

Any better solutions? I’am all ears!
