I found an image of these cool glass bricks on Pinterest a while ago, and thought I'd have a go replicating them in Substance Designer to see how close I could get, as a personal exercise. Turns out they are from Smithfield Market in London.
I *did* add some extra flourishes that weren't in the source reference, like the drip marks, just to spice it up a bit. I also ended up making two materials, one for the concrete including the hexagonal ridged glass, and one for the transparent glass, and combined those in Marmoset Toolbag. Rendered in Marmoset with some post in Photoshop.
Thanks to various art friends for the feedback ❤
Fully procedural material.
