A collection of 30 procedural metal smart materials and 4K PBR texture sets. While the smart materials (.spsm) are designed specifically for Substance Painter 6.2.1 or higher, the included 4K texture maps can be used in Blender's shader nodes or any other software supporting standard PBR workflows. The package also includes over five hours of video tutorials covering modeling, UV mapping, and texturing workflows for hard surface assets.
