This section contains information on the V-Ray for Grasshopper plug-in.



V-Ray for Grasshopper adds a number of nodes for use with Grasshopper's graphical algorithm editor that enable direct rendering as part of the Rhino scene without baking geometry.

Since version 3.06.02 V-Ray's installer for Rhinoceros 6 will automatically install V-Ray Grasshopper without showing it as an opt-out in the installer. If you have Grasshopper for Rhinoceros 5 installed, V-Ray for Rhino's installation will automatically detect it and proceed with installing V-Ray for Grasshopper as well. 



V-Ray Nodes in Grasshopper

There are four tabs in the V-Ray toolbar in Grasshopper: Geometry, Lighting, MaterialRender, and additionally the V-Ray Render Elements Nodes.


A parameter with a bullet point in front notifies about a slot that can receive an input only from another V-Ray node. 


The Scene slot receives an input only from a VRScene file.


Many of the V-Ray nodes in Grasshopper have a Show Controls option in their context menu. The Show Controls option extracts a V-Ray node's parameter controls such as toggles, file path inputs, and color swatches.


V-Ray Script Access in Grasshopper

Rendering in Grasshopper can be initiated through Grasshoppers C# Script and/or GHPython Script components.  For more information, see V-Ray Script Access in Grasshopper.
