Experimenting with some new techniques.
The cliff is from Megascans Moab Collections which I got from Quixel Bridge. Using Transmutr I created a skp file and in Sketchup I split off the portion below the cliff to create a separate area to scatter in D5 with the wildgrass pre-set.
Rendered in D5 and applied a strong weight AI enhance on the cliff alone. Post-processing is just a resize in Photoshop. The model is the EMD SD45 by me alone with the tracks. I used D5 brush to scatter some ballast rocks outside the ballast bed.
The cliff from Quixel Bridge is the Desert Western Cliff Layered XL 04. LOD 0. It’s free from Quixel Bridge by signing up with Epic Games.
The AI enhance really pops out the cliff rock textures.
