Some things have come up in life so I hadn't modelled or posted to sketchfab in about a month... I made this tonight while getting back into the swing of things. It's a hard-surface practise model, as well as some practice with Substance Painter 2. Spent a while trying to get good topology on the details of the mesh, and in SP2 I used lots of procedurals and the mask builder. Honestly, I think this is one of the best pieces I've done, at least from a photo-realism standpoint.
And here's how it looks as rendered from Iray!
