V-Ray 5 Material Library and Light Gen issue due to expired certificate

Overview

This article provides information on how to manually download and set V-Ray 5 Material Library.

 

Issue Description

The V-Ray Material Library and Light Gen HDRI assets may be inaccessible for direct download to V-Ray 5 users. 

For example, after installing V-Ray 5, you might not be able to download and use V-Ray Material Library from V-Ray Asset Editor or generate Light Gen scenarios. Common error messages include:

  • "Something went wrong while loading the library. We were unable to determine if the content you have is up to date with the latest version."
  • "Error loading scenarios. Cannot download http://materials-cdn.chaosgroup.com/mtllib/files-map.json. certificate has expired."

 

Solution

The simplest resolution is to upgrade to V-Ray 6 or V-Ray 7. Alternatively, you can manually download the library and place the asset files as follows:

Step 1: Download Archive

Download the archive with assets from the following link: Download Archive.

Step 2: Extract and Place Files

  • on Windows: extract the files to %USERPROFILE%\Documents\
  • on macOS: extract the files to ~/Library/Application Support/ChaosGroup/

Step 3: Restart V-Ray

After placing the files, restart V-Ray. Note that a message prompting you to download assets may still appear - press “Continue” to safely disregard it.
