Manual Trigger (mtllib.exe): If the library didn't download during setup, you can manually trigger it on Windows by running mtllib.exe, typically located in:

C:\Program Files\Chaos Group\V-Ray\V-Ray for 3ds Max 20xx\bin\mtllib.exe.

Chaos Cosmos Browser: In V-Ray 5.2 and later, you can access an extensive, updated library of materials directly through the Chaos Cosmos Browser icon on your V-Ray toolbar. These materials are downloaded on-demand and stored locally. Common Content Categories
