The VRayScannedMtl material allows the rendering of scanned BRDF material data stored in .vrscan files. These files are produced by ChaosGroup' s own internal material scanner and accompanying material creator software.

note
With V-Ray 6, the Scanned Material doesn't require a separate render license to work correctly.
In However, for earlier V-Ray versions, the Scanned Material requires a separate render license to work correctly. Without a license, the material will render renders with a watermark, otherwise, it should be able to render the scenes.
The scanned material renders the captured appearance of an actual physical material sample, that has been scanned with special scanner hardware. The material goes beyond single-point BRDF capture and can faithfully represent the textured appearance of a large number of real-world surfaces using bidirectional texture function (BTF) approximation.
Because the scanned material simply reproduces the way a physical material responds to light, is has no notion of "diffuse" or "reflection" components, "normal" or "bump" maps.
The .vrscan files tend to be quite large as they need to pack a lot of data (they need to describe the BRDF of the material over its entire surface).
