URP to support Android below v5

Hi there, I recently switched from built-in render to a Universal Rendering Pipeline in attempt to support as many devices as possible.

I understand that for good performance I have to switch off shadows/bake shadows and in general set a lower resolution for most of the settings.

However, even with the lowest graphics settings, when I upload my build to Google Play and visit Testing Tab there, I can see that there is no graphics on older Androids. Isn't URP supposed to work for them out of the box? If not how can I fix that?



I suppose resolution and shadows actually should just make performance worse, but what exactly might be causing such a blank screen?

 

@aleksandrk Thanks for suggestion, I think this is related to Open GL ES 2, rather than Android version. I guess I have to disable some player settings, but I'm not sure which ones exactly. I don't think this is a bug though, just requires some tuning.

I already found that I have to disable GPU skinning (Compute skinning).
Maybe you know something else that breaks rendering on OpenGL es 2?

Here some errors from logcat:

In case someone tracks this thread, I think here is the answer: https://forum.unity.com/threads/uni...ansition-is-not-supported-on-gles-2-0.792945/

 

@aleksandrk yeah, I shared some unity shaders error in the link I shared above. It seems this bug is already being tracked.

 

@aleksandrk Well, I tried to upload development build to Google Play, to see the errors, but it seems Unity doesn't sign development builds, and google doesn't allow unsigned upload? On my personal device there are no errors.

If I upload release build, than those lines above are the only errors in logcat:

Hmm, I commented this void and it started working:
