It…

The crater one can be done with some regular noise and then subtracting some cellular/ voronoi one. I also see "turbulance/plasma" ones...World Machine is also very good for this. I personally don't…
I'm currently working on this planet generator for my physics sandbox space artillery game called Dots In Space. Here are some examples: It is done mostly inside a UE4 Shader/Material with lots of parameters that get randomized. Basically lots of mixing but only 5 textures, which are normal maps with greyscale which often…
