Additional Components

In this step you can opt to install the License Server and V-Ray Swarm. Press the Continue button to proceed with the installation. Check the V-Ray Swarm page for setting up V-Ray Swarm from its designated installer.






Optimize V-Ray for Revit installation by manually setting the location folder where V-Ray is installed. V-Ray Swarm "on" and "off" functions are also available here.

Destination location – Specify an installation location for V-Ray for Revit.

V-Ray Material library – Specify a download location for the Materials Library and Cosmos Assets.

V-Ray Swarm Enabled – When enabled, after the installation is complete, V-Ray Swarm is activated by default.

Don't use local machine – When enabled, the local machine is excluded from rendering. However, V-Ray Swarm continues to use a small percentage of the local machine's resources to communicate with the nodes.

Goal – Sets the desired percentage of utilization of available resources. Computers added to or removed from V-Ray Swarm are taken into account automatically.

Auto-Discovery – When enabled, the installation searches for other nodes in the network.

Tags – Tag this node with a descriptor that defines something about the machine and use it for selective control from inside of Revit. Separate each tag by a comma. For more information, check the Swarm page.






Specify whether the V-Ray License Server runs locally or on another machine.

The Remote option requires the IP address of your V-Ray license server to be filled in the Primary License Server field. Please, leave the port 30304 unchanged. An Alternate License Server is used when the primary one does not respond.





3. The installer first checks for running applications and prompts you to stop them, if there are such. Then it automatically uninstalls all old versions. 





4. Installation is completed. On the last screen resides the usage statistics collection option. See the Chaos Telemetry page for more information or select the  Open the release notes file option to open the release notes file after the installation.




Check Your License

Once the installation of the License Server is complete, you are directed to the License Server local host ( in order to sign in and activate it.


The License Server skips its installation process for two reasons:

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

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


Running V-Ray for the first time

By default, when Revit is launched, the V-Ray for Revit license is not automatically engaged and the V-Ray toolbar is grayed out.




To pull your license and start using V-Ray, press the Enable V-Ray button. When Revit is closed, your V-Ray license will be released automatically.




If you prefer your V-Ray license to be engaged automatically every time when Revit is loaded, use the Obtain License on start-up option.
