I made a short making of tutorial for Chaos Group blog. You can see it there:
https://www.chaosgroup.com/blog/how-to-transform-a-sunny-3d-environment-to-stormy-with-v-ray
I did couple visualizations of a greenhouse made from modular system for a client. Then I wanted something different so I did my private night stormy scene.
All done in 3ds max + V-Ray Next and Photoshop. I used tyflow and Forest Pack for 3ds max and some megascans surfaces as well.
You can follow me on instagram, where I am putting more cgi tests and studies: https://www.instagram.com/jiri.matys_cgi/
