checkonchuck Are only the URP specific shaders SRP batcher compatible or will all the Shaders be SPR batcher compatible by default?
Misaki is correct in that the shaders that are included in the spine-unity runtime unitypackage (as opposed to the shaders in the Spine URP Shaders package) are not intended to be used with URP (or any scriptable render pipeline).
An exception are the UI related shaders Spine/Skeleton Graphic and the like, where CanvasRenderer is separate from the normal render pipelines, these Spine/Skeleton Graphic shader should still be used when using URP.
Any other unintended combination of render pipelines with shaders might look correct in the Unity Editor but might end up with display issues on e.g. a target mobile device.
