Note that Chaos Cosmos is not included in the V-Ray for Maya Portable installation file. You can separately download and install Chaos Cosmos.

To use the Chaos Unified Login (a single login into whichever Chaos application grants access to all Chaos applications) with V-Ray portable installation, download and install separately. 

When using V-Ray from a Portable installation, the EULA needs to be accepted to start a render. A pop-up window will prompt you to accept the EULA the first time you start a render. Batch rendering is an exception to this.

If you are using a V-Ray version older than V-Ray 6, please refer to the Installation from zip guide, as the Portable Installation is not available for those V-Ray versions.

...

Unpack the installation into a suitable location, which you can later use to run V-Ray on any computer. Here is a detailed step-by-step guide:

  1. Download the V-Ray installer executable (.exe).

  2. Open a Command Prompt. Type out: the location of the installer that you just downloaded -unpackInstall= location where you wish to unpack. Alternatively, you can drag and drop the installer and a target folder for unpacking into the Command Prompt to insert their directories. Press Enter to run the command. As an example, you can create a new folder called vray_builds to hold all portable V-Ray builds. Then, you can make other sub-folders and name them according to the V-Ray build version, for example vray_60002_maya2023 . It should look something like this:

    Code Block
    languagepowershell
    D:\Downloads\vray_adv_60002_maya2023_x64.exe -unpackInstall=D:\vray_builds\vray_60002_maya2023
    Section
    Column
    width30%

    After unpacking the installation, your folder structure should look like this:


    D:\vray_builds\
    ├── vray_60002_maya2023\
    │ ├── maya_root\
    │ ├── maya_vray\
    │ └── vray\

    Column
    width10%

     

    Column
    width30%

    Here is an example with two different V-Ray 6 builds for Maya 2023 - each can be deployed with its own shell script and environment.

    D:\vray_builds\
    ├── vray_60002_maya2023\
    │ ├── maya_root\
    │ ├── maya_vray\
    │ └── vray\

    │ ├── maya_vray\
    │ └── vray\

    Column

    The D:\vray_builds location is an example. The Portable Installation can be placed anywhere.

  3. Set the necessary environment variables into a new Command Prompt and run V-Ray for Maya or V-Ray Standalone.

  1. Download the V-Ray installer .dmg file and double-click to mount it. By default, it mounts to /Volumes.

  2. Open a Terminal and type out /path/to/run_installer -unpackInstall=</unpack/target/location>.
    As an example, you can create a new folder called  vray_builds  in your root directory to hold all portable V-Ray builds. Then, you can make other sub-folders and name them according to the V-Ray build version, for example  vray_60002_maya2023 . An example unpacking command should look like this:

    Code Block
