This page provides information on the V-Ray Portable installation.
Please do not use multiple V-Ray installation methods at the same time. If you plan on creating a Portable V-Ray installation for Maya, make sure you have uninstalled any other V-Ray version for Maya.
Overview
The V-Ray installation file (.exe) can be unpacked and used as a portable version. Creating a Portable installation provides several advantages over the regular installer:
The Portable installation allows for setting a custom environment when starting each Maya instance. To compare, running the regular installation multiple times overwrites the V-Ray environment variables.
The Portable installation can be used to run V-Ray for Maya and V-Ray Standalone from any location or even a network drive. That way, multiple users can start Maya along with V-Ray using just a script that sets up the environment variables without the need to run local installations.
Upgrading a Portable installation is a lot easier too, as you don't need to run the installer on every user's computer.
The Portable installation allows for quick switching between different V-Ray versions without reinstalling it.
When installing V-Ray for Maya from a Portable installation file, note that Chaos Cosmos is not included by default in the installation. To add it, you can separately download and install it.
When using V-Ray from a Portable installation, the EULA needs to be accepted to start a render. A pop-up window appears when rendering begins. Only Batch rendering is an exception to this.
Please note that the Portable installation is derived from unpacking the V-ray installation file (.exe). It is not the same as a zip installation.
Required steps to run V-Ray
To create a Portable installation, you need to:
1. Download a V-Ray installation file. Click the button to do so.
2. Unpack the installation file. See the Unpacking the installation file section of this page for further instructions.
3. Set up the environment variables needed to run V-Ray for Maya/ V-Ray Standalone. You can find further instructions on this step in the Environment Setup section of this page.
4. Set up your license. Visit the Licensing section to find out how.
5. Run Maya or V-Ray Standalone.
Unpacking the installation file
Unpacking the installation creates three folders in your specified location, which you can later use to install V-Ray on any computer and in any location you like. Here is a detailed step-by-step guide:
Download the .exe installer.
- Open the Command Prompt. Type out: the location of installer that you just downloaded -unpackInstall= location where you wish to unpack. Alternatively, you can drag and drop the installer and folder into Command Prompt to insert their directories. Press Enter to run the command. It should look something like this:
D:/Downloads/vray_adv_60010_maya2022_x64.exe -unpackInstall=D:/unpacked_installation
- Set the necessary environment variables into a new Command Prompt and press Enter.
Download the installer.
- Open the Terminal. Type out: the location of the installer you just downloaded -unpackInstall= location where you wish to unpack. Alternatively, you can drag and drop the installer and folder into Terminal to insert their directories. Press Enter to run the command. It should look something like this:
D:/Downloads/vray_adv_60010_maya2022_centos7 -unpackInstall=D:/unpacked_installation
- Set the necessary environment variables into a new Terminal and press Enter.
Download the installer, extract the .app file.
- Right-click on the installation.app file and click on Show Contents > MacOS. Here you will find the run_installer file, which is used for this type of installation.
- Open the Terminal and type out: the location of the run_installer file -unpackInstall= location where you wish to unpack. Alternatively, you can drag and drop the installer and folder into Terminal to insert their directories. Press Enter to run the command. It should look something like this:
% /Users/User/Downloads/vray_adv_60010_maya2022_mavericks_x64.app/Contents/MacOS/run_installer -unpackInstall=unpacked_installation
- Set the necessary environment variables into a new Terminal and press Enter.
Environment Setup
The following environment variables need to be set when running Maya with V-Ray.
In the examples below, nnnn is the Maya version, for example 2020 or 2023, etc. For example VRAY_FOR_MAYA2020_MAIN or VRAY_FOR_MAYA2020_PLUGINS, etc.
V-Ray 5 and later come with material presets. To load the presets, the MAYA_PRESET_PATH environment variable needs to be set.
The example directory and version names below are for V-Ray 6 for Maya 2020 on Windows where vray_adv_60010_maya2020_x64_install.exe has been unpacked into D:\vray_builds\vray_60010_maya2020\.

Notes:
1 (1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8) - nnnn is the Maya version. For example, 2023, 2022, 2020, etc.
2 (2.1, 2.2) - VRAY_PLUGINS is used for running the V-Ray Standalone executable that comes with the V-Ray for Maya installation. This is needed to render .vrscene files directly with V-Ray Standalone. An alternative to setting VRAY_PLUGINS as an environment variable is using the config.xml located in vray_builds/my_version/maya_vray/bin/config.xml. You will need to edit the xml file with a text editor and point the [PLUGINS]/vrayplugins to vray_builds/my_version/maya_vray/vrayplugins.
-- Example: Locate the xml file in the location where the build is unpacked, in the examples so far - /opt/vray_builds/vray60010_maya2020/maya_vray/bin/config.xml.
-- Once edited, here's how the line containing the vrayplugins location should look like: <PluginsPath>/opt/vray_builds/vray60010_maya2020/maya_vray/vrayplugins</PluginsPath>
3 (3.1, 3.2) - VRAY_AUTH_CLIENT_FILE_PATH needs to point to the folder that contains the vrlclient.xml file that holds the V-Ray license server settings (IP address and port number). Alternatively, using the tool to set or change your license settings will create the vrlclient.xml file for you at a default location and there will be no need to explicitly define its location the VRAY_AUTH_CLIENT_FILE_PATH variable. However, it might be useful to use the variable to define per-user license settings.
For the case where using the environment variable is the best option for you and you need to create the vrlclient.xml file manually, the example below shows what it should contain:
Setup for V-Ray Standalone
Environment Variables
The portable install can also be used to run only V-Ray Standalone without running V-Ray for Maya. In this case, the number of environment variables to set is reduced.
The list or variables to set requires unpacking the same installation build. Read the Unpacking the installation file section for more details.
The example directory and version names below are for V-Ray 6 for Maya 2020 on Windows where vray_adv_60010_maya2020_x64.exe has been unpacked into D:\vray_builds\vray_60010_maya2020\.

Tags
The [STDROOT] and [PLUGINS] tags in the script are normally replaced with their directories by the V-Ray installer, but when you are using a Portable Installation, you need to replace them manually. The [STDROOT] tag needs to be replaced with the full path to the vray folder in the portable file. The [PLUGINS] tag need to be replaced with the full path to the maya_vray folder in the portable file. The tags are located in the following files:
Linux and MacOS:
maya_vray/bin/vray
maya_vray/bin/vrayserver
vray/vray_netinstall_client_setup.sh
vray/samples/appsdk/setenv39.sh
vray/bin/vraymayaserver.conf
vray/bin/registerVRayServerDaemon
vray/bin/initVRayServerDaemon
vray/bin/vraymayaserver.service
maya_vray/bin/plgparams
Windows:

This is needed to render .vrscene files directly with V-Ray Standalone. An alternative to setting VRAY_PLUGINS as an environment variable is using the config.xml located in vray_builds/my_version/maya_vray/bin/config.xml.

5 (5.1, 5.2) - VRAY_AUTH_CLIENT_FILE_PATH needs to point to the folder that contains the vrlclient.xml file that holds the V-Ray license server settings (IP address and port number). Alternatively, using the tool to set or change your license settings will create the vrlclient.xml file for you at a default location and there will be no need to explicitly define its location the VRAY_AUTH_CLIENT_FILE_PATH variable. However, it might be useful to use the variable to define per-user license settings.
For the case where using the environment variable is the best option for you and you need to create the vrlclient.xml file manually, t he example below shows what it s hould contain:
If you want to use any additional tools like the Irradiance map viewer, the VRIMG to OpenEXR converter etc., then also add to the PATH environment variable vray_builds/my_version/vray/bin.
Please note that by default the V-Ray installer will set the TdrLevel (that is GPU timeout detection and recovery) to 0 (disabled).
