This page provides information about the Geometry in V-Ray for Grasshopper.
Overview
The V-Ray Geometry component translates GH meshes to V-Ray geometry that can be used by the Renderer. A V-Ray Material can be applied to all input objects. If multiple objects and multiple materials are connected to the component V-Ray distributes the materials between the geometries based on their list index. If there is no input material a default gray material is automatically used. If the materials count is smaller than the objects count the last material is applied to geometries indexed higher in the list. If the materials count is bigger than the objects count overlapping geometry is produced. This should be avoided.
To keep track of the objects and materials list order a standard Grasshopper Merge component can be utilized.
Input Parameters
Geo (Generic Data) – Geometries input is expected in this slot.
Mal (Generic Data) – V-Ray Material input is expected in this slot.
Visible (Boolean) – Controls the geometry visibility.
Output Parameters
V Geo (Generic Data) – V-Ray Geometry output. Can be connected to the V-Ray Render's Geometry slot.
Options menu
Meshing Quality – Controls the tessellation of the geometry data. By default the option is set to Low, which could produce jagged reflections on a seemingly smooth surface. Setting a higher option will generate more faces and produce smoother reflections. Note that every increase in the face count will slow down the render process.
Export – Exports geometry data to a .vrmesh or .vrscene file
Notes
- You can use a material with UVW texture to display the vertex color of the geometry. For more information, see V-Ray Material from File.
