The Gamma game controller reveal video was rendered on GarageFarm.NET’s GPU server. The server, with real-time remote access, made it possible for Florian to work on the project like he would on a home computer, with the whole rendering power of 8 Titan GPU cards.
The artist can definitely take the most of visual possibilities given by the Octane render engine, but the real magic happens in his post work. You can see it yourselves on his Vimeo channel or check his compelling concept art projects on Behance.
