I would need to see the project, but basically you need to make sure of a couple of things:
-Is the material for the sprites translucent?
-Are you sure you’re not using the parent component transform to determine the sprites’ rendering position?
-Are you using the translucent sorting policy in the settings, setting the value in the axis you want to use to something? (Usually 1 or -1)
If you have done these things, I don’t think I can help you…
I’ll write if I come up with anything else.
