Setting up V-Ray for Houdini comprises of several steps: installing and licensing through your OS, and then loading the V-Ray Shelf and setting V-Ray as the renderer inside Houdini.

Installation can be done via a pretty straightforward and easy to follow installer as well as via a zip file. Follow the step-by-step guide below to set up the V-Ray installation.

Install Directories

Here you can specify the installation paths for V-Ray for Houdini and the Houdini Packages. Please check if the default folders are correct.

Help make V-Ray even better – Participate in the improvement decisions for future version of V-Ray. No intelligence property is violated when agreeing to participate in the feedback program. Chaos does not gather scenes, assets, materials, etc. What Chaos receives is user preferences on just a few key render settings and the resulting render times. The point of this feature is to improve V-Ray's performance and the user experience. For more information, see the Chaos Telemetry page.

 

 

If you have selected a Local V-Ray License to be installed, you are presented with the Chaos License Server Options.

The Chaos License Server will skip its installation process for two reasons:

  • If it detects a previous installation of the Online License Server on your machine.
  • If you choose the Remote V-Ray license server on the network option.

 

For full information on the Chaos License Server options and settings, see the Licensing section of the documentation.
