Here's a video I did for the tax company, Avalara. I was responsible for creating the storyboards, visual style, models, animation, lighting, and camera movements. The walk cycle of the character was edited and toned down by another animator as requested by the client (Apparently I made my older walk cycle too happy :) ) The Avalara introductory logo, and logo design were not done by me.
The models and animations were created mostly as separate objects in 3D Studio Max, and the actual rendering and compositioning of the scenes done in Unreal Engine 4. UE4's Matinee was used to power the playing of the animations and camera movements, and then the video was finally edited together in After Effects.
Scenes were a mixture of being built to the world space, and built as separate instances.
