could you try designing one that looks like its covered in a very brightly coloured fungus....super organic and phosphorescent looking, maybe covering a far-duller or darker surface like rock or black sand maybe

This sounds like a cool idea! I can imagine this for uranium planet. Thank you for your suggestion @basilmarples 👍

nice! i don't know if youve done one with lots of rivers yet? That would be cool too... rivers of lava or ice maybe? Or just deep empty canyons.... Its exciting! I love the finishes youre getting on them
