A little story,
Aborth, an ex-Navy SEAL and extraterrestrial researcher from the late 21st century, collecting biological traces from the valleys in Scotland, after the massive invasion of Regons, a xenomorph like intergalactic species. The 4-member crewed aircraft is landing in the valley area to bring the collected samples to the central laboratory located in Alaska.
The terrain is generated using LiDAR geospatial data of Sgùrr na Cìche peaks, Scotland. Maps are exported in 4k resolution from Houdini, which was sufficient for masking the landscape layers for this project. For biomes (Trees and Rocks), used the PCG Graph for scattering the assets. Nanite tessellation is enabled for the Landscape Master Material. Indirect lighting in ScreenSpaceGI rather than Lumen to avoid the halo shadowing effect around the boundaries of grass clusters, but most of the distant screenshots are in Lumen.
