This page provides information about the V-Ray Exporter node in V-Ray for Grasshopper.
Overview
The V-Ray Exporter node exports the current scene to a .vrscene or .vrmesh file. The node must be connected to a V-Ray Render component and a valid output file must be set.
Right-click on the component opens a list of export options. Some of them are available only when a Timeline is connected to the V-Ray Render component.
Show Controls - Provides an output file node connected to the exporter. Specifying a valid output file is required for the V-Ray Exporter to work.
Export - Exports a Proxy Mesh (vrmesh) or V-Ray Scene (vrscene).
Export Animation - Exports an animation as a single animated Proxy Mesh or V-Ray Scene file. This function is disabled when there is no animation in the scene.
Export Sequence - Exports an animation as a sequence of V-Ray Scene (vrscene) files, each corresponding to an individual frame. This function is disabled when there is no animation in the scene or if the Output File is a vrmesh.
Open - Opens the specified output file at its designated location.
Currently, animated object creation or deletion is not exported correctly. Every animated object should exist throughout the entire sequence. Mesh faces, on the other hand, can be modified, deleted or created dynamically (vrscene export only).
Note that .vrmesh files do not store lights, camera, render settings or material data. They contain only geometry data and face IDs.
If there is a Timeline connected to the V-Ray Render component, the Export option produces a file based on the current frame while the Export Animation includes the entire Timeline animation.
Right-click on the node to see more options.
Input Parameters
Scene (Generic Data) – This is the scene input slot. A V-Ray Render's Scene is expected here.
Output File (Text) – Specifies the output file location and type. Select .vrscene for a scene export and .vrmesh for a proxy mesh export.
Example
Example scenario of how to use the V-Ray Exporter node. Right-clicking on it and choosing 'Export Animation' creates an animated Proxy Mesh as demonstrated in the VRMesh Viewer's active timeline.
Notes
- VRscene files exported from V-Ray 3.6 for Grasshopper cannot be rendered with the Next version of V-Ray Standalone, V-Ray for Rhino or V-Ray for Grasshopper. There are two workarounds available:
- Open the .gh scheme(s) and re-export the .vrscene files using V-Ray Next;
- Manually edit each affected .vrscene file.
- Open the .gh scheme(s) and re-export the .vrscene files using V-Ray Next;
- Currently, exporting animated proxies having alternating faces per frame is not supported.
