Photogrammetry is used for many new materials - ensuring accurate displacement maps down to the pixel level.
Use unclipped HDRI environments with clean horizons to quickly add a fitting and realistic ambience to any scene.
Many materials come with Substance (SBSAR) files that allow you to tweak them to your needs.
