For about 3 years I also had the privilege of using my artistic and cinematic skills on ReBoot: The Guardian Code as the World Building Supervisor, which is a Hybrid Animated TV Series for broadcast rendered with Unreal 4, with over 3,300 shots created in 4k.
Part of my responsibilities was to build a team of environment artists, onboard them into a new technology (few had previous Unreal experience) that had never been used to render a TV show before, and provide any support needed to produce the highest-quality content in a very short time-frame.
All content below was created in Maya and Unreal 4.
