This can be used to avoid seams in-between non-tileable repeated textures.ĭouble-sided – This option should be enabled only if support for unique front and back face UVS is required. The option cuts the texture in the half flipping one side vertically or horizontally. Mirror U/V – Mirrors the texture in the U and V direction separately. Default color is found in Parameters > Color Manipulation. If the option is disabled, the Default texture color is used outside the 0 to 1 UV square. Tile U/V – Tiles the texture in the U and V direction. Rotate – Rotates the texture (in degrees). Offset U/V – Controls the texture offset in the U and V direction. Repeat U/V – Determines how many times the texture is repeated in the 0 to 1 UV square. A value of 1 takes the first available channel. UV Channel/Set– Specifies the index of the mapping channel data to use. 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. In its present form, the material is targeted at users that need to match exactly a given real-world sample. You can only change the overall tint of the material. you can't change glossiness, increase reflectivity etc. Also, for the moment except for some general tint control, the material is unmodifiable - i.e.

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.Ĭurrently, the material can render only opaque surfaces. 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 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 render license to work correctly. With V-Ray 6, the Scanned Material doesn't require a separate render license to work correctly.
