Discovering the amazing work of RUX (https://www.artstation.com/roggiero3d) reminded me how I used to work and how fun it was.
I was not that good and not into pixel-perfection. Right now I finally found out how to do unwrapping in 3dsmax in a way I can get a pixel-perfect mapping. Took me time but nailed it ; might not be visible on this 1st try (already more to come).
Also I don't like texture filtering xD
