Worked though this Steam Punk Weapon and had a good time of it. Tried to see if I could just use Marmoset 4 texturing tools instead of using Substance Painter for the texturing portion of the project. Just went step by step and equated what might produce similar results for Marmoset 4 and this is what resulted. It was defnitely a tutorial that took some commitment and time. I would recommend knowing these programs fairly well if you go attempting this build. Decided to go with an absinth decorative theme on the weapon.
