It was supposed to be a photogrammetry exercise but after I added the dinosaur a nice picture came out.
the trees and the ground are scans of objects in the park in my neighborhood. some of the scans are used to make lowpoly objects (with quadremesher), while some of the scans are used to make seamless pbr textures, which can be used on any objects.
Did you use any volumetrics in rendering or is the sense there might be some added in compositing, photoshop, etc? Because the “moodiness” is super strong, can only imagine it being pushed further (like your poor CPU/GPU) with mist.
