This Concrete 1 PBR Material contains PNG image maps set at 2048×2048 pixels. This free material can be used in all video game engines that support a physically based rendering workflow, but are optimized for using a metalness/roughness workflow. I have texture sets for Unity, Unreal Engine, and many others. For the users of Blender, Maya, 3DS Max, Cinema 4D, SketchUp and more, choose the “bl” file. These options use the same general configuration.
