I tried to do some short test with awesome Knights sample pack prepared by Jama Jurabaev and Oleg Zherebin.
The goal was to avoid the rainy and foggy places, so desert scenario ;)
During having fun with this one i catch the idea of making some bigger project in the desert environment.
I put some short breakdown of this image on my blog. I will try to publish there some next steps of Petra project there.
