I threw together a scene quickly using the Arizona Desert Assets on the Unreal Marketplace. This was a small paid job done to help an individual developer meet an encroaching deadline. Due to the severe time constrains no custom assets were used, with the exception of the dirt ground material, which I developed using Megascans Mixer. It was a good into to Megascans, and it was fun working with a complete pack of assets.
Although I did not have time to model anything myself, I explored the area using google maps, and created a reference sheet. It would be fun to have a stab at this environment with custom foliage and a higher level of realism!
