Alien Planet - Procedural Terrain in UE4

This is a procedural alien world I made at Voxel Farm.
I used World Machine, Photoshop, Maya and Voxel Studio to create the terrain.
The rock, crystal and bush assets were made in Maya, Mudbox, Photoshop and Speedtree.

A breakdown for the terrain creation can be found here:
