UPDATE
Leaving it here to help others .. I'm an idiot. I had the packages sub folder inside a subfolder. The folder structure needs to look like this or the shaders get screwed up.

Hi

I did a test and made a new project. I could get Spine4 and URP to work correctly. Spine textures worked fine in URP.

But now that I brought it into my real project. It's not working as planned.

I put com.esotericsoftware.spine.urp-shaders-4.0-Unity2019.3-2021-07-01 into the packages folder

installed spine-unity-4.0-2021-10-02.unitypackage without red errors

and can get the normal URP sprite shader to show the goblin.

I'm stumped.. any ideas? :wounded:
