This page provides information on the VRmat Converter standalone tool.

Since V-Ray 6, update 1, this tool has been deprecated. Use the .vrmat exporter from the V-Ray menu instead.



The V-Ray VRmat converter converts materials in 3ds Max to .vrmat files that can be loaded using the VRayVRmatMtl material.
The usual workflow for .vrmat files is:

  1. Use the standard 3ds Max Material Editor to create V-Ray materials for the scene and assign them to objects.
  2. Use the VRMat Converter to save those materials to .vrmat file(s).
  3. Open a different scene, and use VRayVRmatMtl to load .vrmat file(s) into the current scene.

(If this tool doesn't appear on the Tools menu, see Notes below.)

.vrmat Converter

LoadLibrary – Loads a material library file that was previously exported from 3ds Max. 

Use current LIB – Uses the current material library from the scene. 

Covert LIB to .vrmat – Converts each material in the library to a separate .vrmat file. 

Convert LIB in one .vrmat – Converts all materials in the library to a single .vrmat file. 

Pick Convert Material – Selects a single material to be converted to a .vrmat file.

Convert Scene Materials to .vrmat – Converts all materials in the scene to separate .vrmat files.



  • In order to see the V-Ray vrmat converter option on the Tools menu, V-Ray needs to register menus inside of 3ds Max. Normally, this is done by the V-Ray installation automatically, but in case the menu option is missing, it can be registered manually by entering the registerVRayMenus() command in the MaxScript listener.
