Both the Vending Machine and French Fries materials are fully customizable and procedural.
The Vending Machine Material allows you to change the number of rows and columns of soda cans, as well as the amount of each soda brand. It was solely made on Substance Designer with every volume sculpted with a height map within the shader.
The French Fries Material is even more customizable as it lets you define a custom mask for the fries placement and you can change the 2 sauces or chose to remove one of them or both. The fries were sculpted on ZBrush by Violaine Dedieu and were then made into 4 separate height maps.
