I was approached by Flipped Normals to make a full-length prop tutorial, and I eventually settled on making this coin-operated gas meter from the mid 20th Century. Apparently many people in Britain have fond memories of the Gas Collector coming round to empty them of pennies!
Tutorial will be coming soon - keep an eye on Flipped Normals' social channels for its release!
Modeled in 3dsMax, texturing in Substance Painter (with Photoshop for the stickers) and presented in Marmoset Toolbag 3.
