I worked with Weforge to create a new skin for their Space Shifter asset, to give it some Aussie flavour. I remade a Substance Painter file so that we could make new weapon skins simpler and faster. I also optimised the old model to bring down the polycount and draw counts.
I used colour ID, Material ID, and UV masks from Marmoset Toolbag (edited in Blender) for the colour masks.
