This page provides information on the V-Ray Asset Browser, available for 3ds Max 2018 and above. 



V-Ray 5 comes with its own extensive V-Ray Material Library designed to cover detailed resolution for your realistic renders. V-Ray Asset Browser eases navigation in this library by providing high quality material previews, content filtering and quick search of the hundreds of materials available.


UI Path: ||V-Ray Toolbar|| > V-Ray Asset Browser

||V-Ray Toolbar|| > V-Ray Asset Browser

If the material library has not been installed together with your V-Ray 5 this button will download it for you. Once the library is available, it serves to open the V-Ray Asset Browser.


Material Library Installation

By default, the material library is downloaded as part of the V-Ray installation process.

If you skip to download it then, you can initiate the download process by pressing the V-Ray Asset Browser button in the V-Ray Toolbar.

Alternatively, you can download it manually by executing the mtllib.exe file located in C:\Program Files\Chaos Group\V-Ray\3ds Max NNNN\bin. 

The default download directory is C:\Users\USERNAME\Documents\V-Ray Material LibraryIf you need to change it, use the following command line:

mtllib.exe -targetDir="C:\path\to\mtllib"


If the file is executed directly, without a command line, the downloader checks for the VRAY_MTLIB_DOWNLOAD_DIR environment variable. You can set it like so:

set VRAY_MTLIB_DOWNLOAD_DIR="C:\path\to\mtllib"


If none of the above is set, the downloader uses the last download location stored in the registry. Navigate to "HKCU\Software\Chaos Group\V-Ray Material Library", REG_SZ key "Download Path". The "Download Path" key is created or updated after successful material library download.


The default location is C:\Users\USERNAME\Documents\V-Ray Material Library.


After the download is complete, make sure that 3ds Max knows where to look for the library assets. In File > Project > Configure Project Paths > External Files add the Material Library folder.
