I started this project to learn X-gen in Maya. It was sculpted in Zbrush and I was intrigued by the overall character. I've never played the game but Old men who can fight look cool. Like Mai pei from kill bill and Yamamoto from Bleach anime.
Do you seethe sword details in the above picture? It was a worked on in a haphazard way, there is a correct way to do this in Zbrush which gives a much cleaner look and edges. However times have changed and now I do such details not in zbrush but in Substance painter(One more reason to keep learning). As I keep expanding my horizons I learn new tricks and faster ways to make things. Below is the example of painting a height map in Painter.
So I went and made UVs ad took the base meshes in substance just like the sword mesh above and started adding some material details. Here are a few renders with Arnold. And I love B&W renders, Basically just check the Luma channel in render view to see how the values read and then I change materials if required.
