Hello everyone. I am working on a Unity application that will create procedurally generated planets. The way I'm planning to do it is to create 6 planes (or a cube), apply Perlin's noise heightmap to them (plus some soil and hydraulic erosion algorithms) and then map my new cube to a sphere - http://mathproofs.blogspot.com/2005/07/mapping-cube-to-sphere.html .
The problem is - I believe cannot simply use Unity's heightmap tool to apply my heightmaps, since it only works with surfaces that are facing up. Could someone more experienced with Unity help me out with this one? Is it possible to apply my heightmaps to all 6 faces of the cube?
