Thanks, that was meant to be some kind of retro shader - you can adjust the "blockiness" in the editor. Basically it picks the closest color to a limited set of colors with a kind of random dither.
I wanted to make some kind of crappy 8 bit/CGA no Man's sky but - funnily enough - as it turns out making procedurally generated universes with physics that aren't completely broken is rather difficult. I did make a star that looked OK, might post that at some point
