This guide provides steps on installing V-Ray for Maya.

Please check the system requirements before installation. The V-Ray installer will automatically remove any previous versions.

If you experience any problems, please check the Troubleshooting section.

Installing V-Ray for Maya gives you access to: 

OS Specifics

Before running the installation, make sure your Windows account has administrative privileges.

Run the installer. Windows may ask you for permission to run the installer with administrator privileges. Please confirm.

Before running the installation, make sure your macOS account has administrative privileges.

Mount the downloaded .dmg file by double-clicking it and running the V-Ray Installer.

Follow the instructions of the installer.

Starting with version 5.20.00, V-Ray is notarized. For earlier versions, information on how to run the macOS installer safely on macOS Catalina and later can be found on the Installation of Chaos Cloud Rendering Client App page or in Apple's How to open an app that hasn’t been notarized or is from an unidentified developer article.

Open a terminal and navigate to the location where the installation file was saved (vray_install_dir in the example below).

Ensure you have permitted the Installer to run as an executable. That is done with the command chmod +x.

Follow the instructions of the installer.

# For example:
$ cd vray_install_dir 
$ chmod +x vray_adv_60000_maya2022_centos7
$ ./vray_adv_60000_maya2022_centos7
# Follow installer instructions 
$ exit

Some Linux GUI distributions may not be compatible with the installer's GUI. In that case, run the installation with the -gui=0 attribute.

# For example:
$ cd vray_install_dir 
$ chmod +x vray_adv_60000_maya2022_centos7 -gui=0
$ ./vray_adv_60000_maya2022_centos7
# Follow installer instructions 
$ exit

Running the Installer

End User License Agreement

Please take a moment to review the License Agreement.

V-Ray type

Advanced settings

Full – Includes all components as described in the Overview section. It will allow you to use V-Ray in Maya, run V-Ray Standalone or a V-Ray render server for Distributed or Network Rendering.
Standalone only – Installs only V-Ray Standalone and V-Ray render server. Choose this option if you only use this machine for Distributed Rendering.
Add firewall exceptions – Automatically add firewall exceptions so Distributed Rendering and V-Ray Standalone can run uninterrupted.


Here, you can specify the installation paths. Please check if the default folders are correct.

Help make V-Ray even better – Participate in the improvement decisions for future versions of V-Ray. No intelligence property is violated when agreeing to participate in the feedback program. Chaos does not gather scenes, assets, materials, etc. This preference can be changed anytime from V-Ray Render Settings > Settings > About V-Ray > Feedback program settings. For more information, see the Chaos Telemetry page.


In this step, specify whether the Chaos License Server runs locally or on another machine.

If you select Remote licensing, you have to enter the IP address of your Chaos License Server in the Primary License Server field. Leave port 30304 unchanged. An Alternate License Server can be used for redundancy in case the primary one does not respond. The License Server will not install when the Remote option is selected. When Local licensing is selected, the Chaos License Server is installed with V-Ray.

For information about the advanced Chaos License Server installation settings, visit the Advanced Installation page.

Chaos License Server Options

At this step, you can choose where to install the Chaos License Server.

Migrate data during installation – When enabled, it transfers all of your settings made with older versions of the License Server, such as proxy settings, etc. Disabling this option makes a clean install of License Server with any custom settings from previous installations reset to their defaults.

Add firewall exception – Allows the default licensing port (TCP 30304) in the firewall. If you disable it at this step, you must manually add firewall exceptions later. This option is available for Windows OS only.

V-Ray installation is successful.
