Photo scanned textures present an unrivaled level of detail. Textures must be baked from a photo-scanned log on to a lower polygon-count mesh for efficient use in baking. From this bake can textures be exported from Agisoft Metashape as basecolor, normal. ambient occlusion, and height maps. A simple translation show below in Substance Designer will allow that scanned texture to be used in a PBR workflow.
