Sorry, for your question, what the actual issue is:

• When I'm running the Shader on mobile, the Sprites will not be displayed all. Maybe they appear / disappear (flickering / blinking) at runtime. But this only appears with SpriteRenderer. On Spine specific objects its allright. Also with FerrLib (ground plugin).

I tested it times ago with only one Sprite in the scene with a new project and this worked well.

I'll try another time, maybe with multiple Sprites in the scene
