I'm back to working with full CG environments. I have used some kitbash together with other own models, I have even severely modified some kitbash models, to make them hard surface and that they look with the best production quality. Yes, hard work, but some lowpoly or cheap kitbash libraries they look awful sometimes.
With the usual aovs I get from Vray, I've done the post-production and retouching of the renders in Photoshop.
For the trees and terrain, I have used Gaea Quadspinner and generated some random trees with SpeedTree.
It is a work of patience and precision to achieve a level of cleanliness and detail that will be appreciated in the final result.
