My newest real-time model is Siegfried from the Fate series, namely Fate Apocrypha and Fate Grand Order.
I sculpted him in Zbrush, Retopo'd in Topogun, UV'ed, rigged, posed, and assembled in Maya, textured in Photoshop and Substance Painter, and rendered in Unreal Engine 4.
The eye materials are by Epic Games, and the hair/skin material is based off of their examples.
The hair and some materials were really challenging to make, especially since both anime hair and white hair look quite unrealistic in most media. I tried my best, while using references like final fantasy games.
