I’d like to create a surface like this with a displacement modifier… but then I need to find the right kind of texture… Closest I found so far is the ocean displacement, but it’s not quite right.
this is REALLY difficult to do with procedurally generated textures, at least if you want it to look good. you can use voroni to get a base, but after that id actually look into sculpting it and then doing a retopo.
you can also sculpt on a square, and create alphas from geometry.
