A few good bits in this article, where GTA V's enviroment and its graphics is under the knife. http://www.adriancourreges.com/blog/2015/11/02/gta-v-graphics-study/
What a coincident Yea i enjoy searching out and finding these articles. In my mind ive already made acouple of levels for Beamng, that looks amazing. IRL though... few has passed playing around in world editor-stage lol.
I see this has been moved. I would have left this in 'Content Creation'-subforum due to the fact that it has alot of useful information about building the enviroment, tricks to use when building your own terrain.
I went through the whole thing as well and it's really cool. Very informative! Thanks for posting, I love stuff like this. I was blown away by the graphics in GTAV and having an inside look at how they were done is very cool.
