To run V-Ray, you have to:
Overview
V-Ray installer automatically uninstalls any previous versions. Uninstalling V-Ray from Revit does not uninstall Chaos Cloud Client, Chaos Cosmos Browser, Chaos License Server, Chaos Unified Login and V-Ray Swarm. Those can be uninstalled separately if needed.
This guide is to serve as a reference for installation of V-Ray for Revit.
A complete installation of V-Ray for Revit consists of:
- V-Ray
- V-Ray License Server
- V-Ray Swarm
- Chaos Cloud Client app
- Chaos Cosmos Browser service
- Chaos Unified Login
Installing V-Ray for Revit gives you access to:
To start the installation, double-click the installation file. The V-Ray installer automatically removes any previous installations. This allows seamless upgrade from previous versions. If you experience problems, manually uninstall the previous versions to perform a clean install. See the Uninstall V-Ray page for more information.

Click the Continue button to proceed with the installation.
Settings
Optimize V-Ray for Revit installation by manually setting the location folder where V-Ray is installed. You can also enable distributed rendering via V-Ray Swarm upon installation. That way, you won't need to enable it from within the V-Ray for Revit UI.
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.
The settings below become available after checking the V-Ray Swarm Enabled checkbox.
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.
Licensing
In this step, you can specify whether the V-Ray license server runs locally or on another machine.
- If you select the Local licensing option, you need to install the License Server on your machine. See the Chaos License Quick Start Guide for a walkthrough.
- If you select the Remote option, you have to fill in the IP address of your V-Ray license server in the field Primary License Server. Please leave the port 30304 unchanged. An Alternate License Server is used when the primary one does not respond.
V-Ray installation is successful.
