I didnt do anything other than install unity 2022.3.62 (newest subversion), download spine, add a spine model from a project that has the same issue and tried to make a windows build.
In the SampleScene, I have 2 models with the URP/Spine/Sprite shader and the URP/Spine/SkeletonLit shader, which seem to be broken after compilation. In editor they seems fine.
Minimal Example Project:
Brut-225/URP-Spine-Bug
(uses runtime 4.2, csharp 4.2 & urp 4.2)
Any help would be appreciated.
