@Fewes: dang, those are some sexy rocks! Is this using DX11 tesselation or something? Do the rocks and caves share only the materials or it's the same mesh as well?
well just playing around with the sculpting in blender to produce this simple 'low' poly rock face. everything was baked from a higher poly single rock. i suck at photoshop and was to lazy at the time to 'search' for a rock texture, so i did the texture, procedurally in blender. Not the greatest feat, but it works so so…
