Directional light not lighting normal in material on mobile

I am using a directional light with my sky sphere.

On desktop you can see light shines on the normal in the material:

On mobile, it does not:

When i enable cast shadow on the directional light, it enables a little bit of the lighting on mobile (you may need to zoom in to see, but it’s there)

Questions:

  1. Why does enabling cast shadows on the directional light, enable some of the lighting to appear in the normal in mobile?
  2. How do i get the light to look the same as in desktop? What options am i misunderstanding here?

I’ve been on this for about 15 hours now with not much progress.

Anything i can add to this to make it easier to answer?

This is relevant: Mobile Previewer | Unreal Engine Documentation - If i change to android preview renderer i can reproduce the poor lighting on the sea

Any chance someone has any thoughts on this :slight_smile:
