Generic props for an upcoming UE4 project. Optimized for realtime use, maps are mostly 2048^2 (albedo, normal, packed roughness/metallic/AO). Renders are in Toolbag 2.
In some cases I made my own reusable base materials in Substance Designer. Photoshop was used to create details and alphas which were applied in Painter.
For the cardboard boxes, I learned some ZBrush tricks from Alexander Sychov's storage warehouse breakdown (https://www.artstation.com/artwork/1og1Z) and used these substances by Luc Chamerlat as a base (https://www.artstation.com/artwork/9g4wq)
