The Easy Environments series for DAZ Studio and Poser combines high-res Skyboxes (6x 4096x4096) with terrains fit for close range shots.
Close-to-the-floor cameras, steep camera angles which would be impossible with skydomes, seemingly huge landscape shots ...it`s all possible with those sets.
'Mountain Trail' features a trail winding up the side of a mountain. This set makes really good use of the advantages of skyboxes. You can do pretty cool downwards shots, giving a good feel of being really high up in the mountains.
Lighting for Poser and DAZ Studio is included.
The Skybox can be loaded separately for easy use with other scenes. The file format is Poser pp2, all DAZ Studio materials load automatically.
