Quartz 001 is a seamless PBR material built for production use. Base color, surface normal and roughness arrive in register, backed by the usual supporting passes. Textures are authored at 1K for crisp detail under camera push-ins. Perfect for caves, ruins and mountainsides that need honest stone character. It is tuned for Redshift, Corona, Blender and Unreal Engine, so look-dev starts from a correct baseline. A solid foundation surface that lets the rest of the scene shine.
