Overview

...

Installing V-Ray for Houdini from a .zip file provides several advantages over the regular installer:

  • The ZIP installation allows for setting a custom environment when starting each Houdini instance. In contrast, running the regular installation multiple times overwrites the V-Ray environment variables.
  • The ZIP installation can be used to run V-Ray for Houdini and V-Ray Standalone from an arbitrary location or even a network drive. That way, multiple users can start Houdini along with V-Ray for Houdini using just a script that sets up the environment variables without the need to run local installations.
  • Upgrading a ZIP installation is a lot easier too, as you don't need to run the installer on every user's computer.
  • The ZIP installation allows for quickly switching between different V-Ray versions without reinstalling it.

Windows
To deploy V-Ray using the ZIP archive instead of the installer, follow these steps:
  1. Unzip the V-Ray for Houdini archive.
  2. Move it to a location of your choice (e.g. "D:\V-Ray").
  3. Place the "vray_for_houdini.json" file under "$HFS/packages".
  4. Edit the "vray_for_houdini.json" and set the "INSTALL_ROOT" variable to point to the location of the V-Ray files (e.g. "INSTALL_ROOT" : "D:/V-Ray").
  5. Start Houdini.
