This is the Arch Vis Industrial set that I'm working to add to the Unreal and Unity Marketplaces. This isn't nearly all the pieces in the pack! There are, and will be, many more.
It will be a living product, in that I will add pieces to it each month.
I wanted a steampunk meets "found object" kind of vibe from this stuff. A heavy, lived-in kind of feel.
