Is all lighting done with a directional skylight or do you have other lights in the environment too?

Caves have point lights because they just get really dark.

We have a skylight, we have like one directional light which is like the sun and as it arcs the light changes with it and the moon as well and that can all be affected by things like fog and post-processing volumes that we place all around the world as well.

It's possible to get chickens in the game.
