The Easy Environments series for Daz Studio and Poser combines high-res 360° Sky & Landscape backgrounds with terrains fit for close range shots.
"Witchcraft: Eclipse" features a lovely bonfire on a small clearing as geometry.
The skysphere/HDRI shows a huge moon starting a solar eclipse, stars are showing between the clouds. The file formats are native .DUF for Daz Studio 3Delight and Iray, and .PP2 for Poser.
Lighting is included for all versions (Iray through the HDR environment, 3Delight parented to the skysphere).
