If the contribution of reflections falls below this threshold, the reflections are not traced. A value of -1 means that the reflection bounces are controlled by the global V-Ray trace depth in the Global switches rollout of the Renderer Settings.Ĭutoff – A threshold used to speed up reflections. Trace Depth – Controls the number of reflection bounces. 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).įor more details on VRscans, please see the Chaos Scans documentation space for information on downloadable sample scenes and Frequently Asked Questions or visit the website. 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.īecause 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 scanned material renders the captured appearance of an actual physical material sample, that has been scanned with special scanner hardware. Without a license, the material will not show its UI and will render with a watermark, otherwise, it should be able to render the scenes. However, for earlier V-Ray versions, the Scanned Material requires a separate license to work correctly. With V-Ray 6, the Scanned Material doesn't require a separate license to work correctly.
