Substance Designer Rainy Concrete demo

Created in Substance Designer 5 for the Polycount Bi-Weekly Substance Challenge, rendered in Marmoset Toolbag 3.

For this one I took it a bit further and made two separate substances. One for the actual sewer drain, one for the concrete it sits on.
The concrete has a parameter on a slider that makes rainy puddles on a scale from 0 to 1. Had a lot of fun making this.
