this is how I made the terrain brushes,
for the mountains as example I first used to create this base terrain in #blender with this geometry nodes setup, then sculpted it a bit and in the end...
I decimated the mesh to give it a unique stylized look.
Similar terrain brushes I created out of a base, that I created with the landscape plugin un blender, or others from #materialmaker
