Why?

@LeMagicBaguette makes sense to me

@That1SpaceDude it’s either on or off. My best guess is that they just chose off because it happened to default to that, and there was little justification of picking one over the other.

@Seeya i am aware, just why is it always off by default? it's annoying having to turn on surface physics whenever you make a rocky body

@That1SpaceDude So you can make gas giants and stars

@Luckwut i know that but why is it there in the first place?

you need to enable them in planet properties (place where you can put description, set planet gravity, etc)
