Hi everyone,
The following shader works fine in the editor and on Android devices, but is rendered completely black on iOS. Does anyone know how to fix this?

I hope you have the original uncompiled shader for your own sake. If not, what you have is pure evil and shame on whoever gave/sold you that.

Is your Graphics API on iOS set to Metal? Because that shader isn’t compiled for Metal.
