Offline - Vray 6 Material Library Download

Cause: Antivirus software or Windows Defender is blocking the asset packaging.

Solution:

Bottom line: Download through your official V-Ray 6 installation or Chaos account. The library itself is a one-time download and works fully offline after that.

To download the V-Ray 6 Material Library for offline use, you must use the V-Ray Material Library Downloader included with your installation. Chaos no longer provides a direct "zip" link; the assets must be downloaded through the official utility to ensure compatibility. 📥 How to Download for Offline Use

The library is approximately 9GB to 12GB. Ensure you have enough disk space before starting. Locate the Downloader:

Windows: Go to C:\Program Files\Chaos Group\V-Ray\V-Ray for SketchUp\extension\vrayappsdk\bin (Path varies slightly for 3ds Max or Maya). Look for mtllib.exe. Run via Command Prompt: Open CMD as Administrator. Drag mtllib.exe into the window. Add this command: -directory="D:\YourCustomPath" Press Enter. Automatic Download: The utility will pull all assets from Chaos servers. It saves them to your specified folder. Set the Path in V-Ray: Open your V-Ray Asset Editor. Go to Settings > Paths.

Point the "V-RAY_MATERIAL_LIBRARY_RESOURCES" to your new offline folder. 💡 Key Benefits of Offline Storage No Internet Required: Keep working during outages. Speed: Materials load instantly from your local drive.

Portability: Copy the folder to a secondary workstation or laptop.

Consistency: Ensure the whole team uses the exact same asset versions. ⚠️ Important Notes vray 6 material library download offline

Authentication: You must be signed into your Chaos License Server for the downloader to validate.

Updates: Chaos occasionally adds new materials; run the downloader again to "sync" and grab only the new files.

Cosmos vs. Library: V-Ray 6 leans heavily on Chaos Cosmos. For Cosmos assets, you must download them individually through the Cosmos Browser, but they remain cached on your drive afterward.

If you tell me which host app you're using (3ds Max, SketchUp, Rhino), I can give you the exact file path for your downloader.

Starting with V-Ray 6, Chaos Group has transitioned the Preset Material Library into the Chaos Cosmos Browser. While the library is cloud-based, you can still download the entire asset collection for offline use on machines without a continuous internet connection.

How to Download the V-Ray 6 Material Library for Offline Use

If your installation did not include the full library or you need to move it to an offline workstation, follow these steps: Locate the Downloader Tool (mtllib.exe):

Navigate to your V-Ray installation's bin folder. For Windows, this is typically located at:C:\Program Files\Chaos Group\V-Ray\3ds Max NNNN\bin or C:\Program Files\Chaos Group\V-Ray\Maya 20XX for x64\maya_vray\bin. Cause: Antivirus software or Windows Defender is blocking

You can also find the V-Ray Material Library Downloader shortcut in your Windows Start menu. Run as Administrator: Right-click mtllib.exe and select Run as Administrator. Specify the Download Directory:

The tool will prompt you for a location. The default path is usually %USERPROFILE%\Documents\V-Ray Material Library.

If you are preparing a "sneakernet" drive for another machine, point the download to your external storage device. Execute the Download:

Confirm the path and start the process. The library requires approximately 8.5 GB of free space. Installing the Library on an Offline Machine

Once you have the assets on a portable drive, you can install them on a machine without internet access using the Chaos universal installer:

Place Files Correctly: Move the downloaded material folder so it sits directly next to the V-Ray universal installer file (.exe). Do not rename the folder.

Run the Installer: Launch the V-Ray installer. It will detect the local material files and install them from your disk rather than attempting a cloud download.

Configure Paths: In your 3D software (e.g., 3ds Max), ensure the external file paths point to the library assets. Go to File > Project > Configure Project Paths > External Files and add the main library folder and its Assets subfolder.

How to install the material library in offline mode? - Chaos

You cannot download this directly from inside 3ds Max/SketchUp/Rhino if you are currently offline. You need to use a machine with an internet connection.

  • Download the File: Save the file to a USB drive or external hard drive so you can transfer it to your offline workstation.

    • V-Ray 6 utilizes a vast library of pre-rendered materials, textures, and HDRIs. By default, the V-Ray installer does not install the entire library (which can exceed 30GB) to save disk space. Instead, it uses a "Download on Demand" feature where assets are streamed from Chaos Cloud as they are used.

    For secure studios, offline workstations, or render nodes, this default behavior is undesirable. A full offline installation requires bypassing the default installer logic and manually mapping the library path.

    Cause: The path mapping in V-Ray is looking for an online URL instead of a local C: drive path.

    Solution:

    If V-Ray doesn't automatically detect the new library path, you may need to point it there manually.

    For 3ds Max:

    For SketchUp / Rhino / Revit:
