Sand 003 brings a refined stone look with the channel coverage a modern shader expects. Every map is aligned to a shared scale, so albedo, normal and roughness stack without drift. Resolution lands at 1K across the stack, so detail stays intact at any framing. Great for environment art that leans on natural rock and dressed stone. It is tuned for Unity and Cinema 4D, so look-dev starts from a correct baseline. A solid foundation surface that lets the rest of the scene shine.
