Randomly generated planets (parts)

Hi, I’d like to randomly generate a sphere planet with some hills that vary in size, I’d preferably like to use parts when generating.

#2

Well I think the hard part is turning it into a circle I know how to make a good map thats generated with a map

I just merged math.noise to make the hills / biomes / rivers / oceans
But it would be really hard to make it a circle ( I think )

Ah thanks, I heard of math.noise and experimented with it but I have no idea how to make it sphere.

#4

Yeah there would be gaps and stuff in the world I don’t know how to make it look good
And I would have to merge the edges of the noise function it would get pretty messy really quick

I think there 100% is a way to do it efficiently though

Sorry I miss typed I was trying to make one that is a sphere with hills.
