I made this low poly short sword when I was first setting out to learn 3d. I was pretty timid about color at that point so I kept it monochrome.
I really liked the design and thought I should do something with the piece. The answer turned out to use the old diffuse as a height map (with a couple edits) and start masking off materials in Substance Painter. At the end of the process it was nice to see a forgotten model in an entirely new light.
