This whole project started with wanting to model a cool hard surface helm--dug around a lot for concept work and finally settled on 'Ninja' from Metal Gear, was honestly my first real attempt at creating an asset like this from just poly modeling--moderate amount of frustration but the end result was worth. The helmet was also textured in Substance Painter with various grunge masks/edge wears.
The body was originally a base mesh that was a polygon soup of topology, which required retopo, or at least my amateur understanding of it. Seperated the good bits, tagged materials, applied materials, then baked.
