I have a skybox setup, and I would like to have it lighted without using DirectionalLight , because it creates a large aura at the source point—which is not desired.

I need ambient light without an origin point that is visible. Is that possible?

The idea is to make a star skybox with stars that aren’t gray, but fully white - lit by a light, that has no origin (as the distant stars are themselves the lightsource so to speak)..

In meantime I decided to just remove the lightPicker from the material, so it won’t shade parts of it based on depth. Still wish I could control it a little more than swapping materials from photoshop

Tweak the specular, gloss and ambient properties of your material (when using a light-picker with lights) to get rid of the glossy highlight.

But why would you want to light the sky box at all? The sky box simulates a sky that is infinitely far away. Nothing in your scene could realistically change what the sky looks like.
