Hey there,
I have upgraded my project to Unity 2020.3.3f1 (latest) and encountered troubles with something that previously worked:
I have been using the Unity "SpriteRenderer" component together with materials that used the Spine VertexLit (Sprite) Shader.
For some reason, this does not seem to work anymore, as I can't see the sprite at all anymore.
It does not throw an error or get pink, but it's just completely invisible.
No matter what settings I configurate, it does not help. Write to Depth does not help either.
Any idea what might be causing this weird bug?
