This is some of the work I did for Destiny 2.
My responsibilities were to create the non-playable areas in Destiny 2. So, terrain, modeling, clouds, fx, animations, global fog, global lighting, and more. Our team is very cohesive and we share a lot of asset creation task. I can't take 100% responsibility for any sky team creation, and wanted to give credit to:
The masterful guidance of Mark Goldsworthy, and Eric Cassels.
