Shatterline - Rock creation technique with UDM

Unified Detail Mapping (UDM) in this particular case is used to obtain large shapes when viewed from a distance.
Since the close up detail is provided in the regular tiled textures, with the UDM map we show great details after baking highpoly from ZBrush.
At Shatterline, we used this method to create large cliffs, rocks, trees, etc.

For the rock and moss tile materials, I used scanned textures from our library with polished in Photoshop.
