This is a character I used as a test case in the Marmoset Toolbag 4 Beta. The idea here was to see to what extent I could use the baking, texturing, and rendering tools in TB4 to quickly build a character using as few software packages as possible for a rapid look dev workflow. I'd say that effort was largely a success as I was able to only use Zbrush as the modeling and UV tool and Marmoset helped me take care of the rest, with a little bit of help from Maya for some final polish.
I'm honored to have been part of this beta and had loads of fun building this character with Marmoset almost entirely from start to finish.
You can find this model being used in their Learn Toolbag video's chapter on Libraries:
