I ended up separating the mesh into several pats so I could alter the material in Marmoset piece by piece. I mainly did this to adjust the secular map properties.
While taking these renders I ran into a problem Marmoset has with its alpha threshold. When I adjusted that slider for the hair alpha the jacket got these really strange speckled shadows all over it. I found out that to fix this problem, all I had to do was move the alpha threshold slider for the jacket to the right slightly and the shadows would go away.
Unlike my other videos, this one has been uploaded in HD so you can get a much better look at the model. If you scroll through, I have medium shots and close ups as well.
