I spent 3.5 years at Sony as part of the UI team taking the entire UI through a Scaleform + Actionscript based UI into several UMG iterations. UMG implementation yielded major performance increases, as well as a more streamlined iteration process.

I built the Radar and Weapon Wheel systems in these videos from scratch in BluePrint, as well as many of the tweening and base systems used throughout the rest of the UI.
