Convert V-Ray Displacement modifier to V-Ray Proxy or 3ds Max geometry

Since V-Ray 5, V-Ray has an experimental option that allows converting scene objects with a V-Ray Displacement modifier to a V-Ray Proxy (.vrmesh) file. Once converted to а V-Ray Proxy object, the geometry can be also imported as native 3ds Max mesh.

Export displaced geometry to a V-Ray Proxy file

1. Select the object in the 3ds Max viewport. The object should have a V-Ray Displacement modifier in 3D Mapping mode.
2. Open the 3ds Max MAXScript Listener from the Scripting menu.

3. In the Listener, run: 

   $.VrayDisplacementMod.write_vrmesh="C:\\path_to_file.vrmesh" 

   Replace the path and file name with your desired .vrmesh output.

4. Start the V-Ray Rendering process to export the .vrmesh file during the pre-rendering stage.
5. Stop the Render once the .vrmesh has appeared in the folder.

6. Revert to the normal rendering behaviour by running:

   $.VrayDisplacementMod.write_vrmesh="disable"

Import the .vrmesh back into 3ds Max

After exporting, you can bring the proxy into your scene and convert it to a native mesh if needed.

• Drag and drop the .vrmesh into the viewport, or use the V-Ray Proxy Importer.
• To convert the proxy to an Editable Mesh, use the Import as mesh option in the V-Ray Proxy.

• If some edges appear hidden after import, select the edges and enable the Visible option in the Editable Mesh modifier.

   

Limitations

Currently, only V-Ray Displacement with 3D Mapping type can be converted with this script.

2D mapping and Subdivision types do not work with it.
