The Easy Environments series combines high-res 360° Skysphere/HDRI backgrounds with geometry to place your characters on.

ExoPlanet IX, the ninth entry in the series, is a desert planet, hostile to any life.

The set includes 4 HDRI/Skysphere Options: Default, Sunset, Big Planets, Big Planets + Sunset.
You can hide the whole Rocks Group to get a dunes-only look at the center piece.
The dune surface offers 6 Morphs to dial in foot-trails: 3 below the rocks, 1 up the main dune, 2 along the dune edge (see clay/overview preview).

The file format is native .DUF for Daz Studio 3Delight and Iray.
Lighting is included for all versions (Iray through the HDR environment, 3Delight grouped with the skysphere).
