Plugin Installation

Decompress and copy the PresenZ Houdini folder.

Edit your houdini.env as following (windows):

PRESENZ_LICENSE= "path/to/the/lic/file"
PATH = "$PATH;/path/to/presenz/plugin/bin"
HOUDINI_DSO_PATH = "/path/to/presenz/plugin/houdini;&"

Please consult Houdini documentation for more details.

Obtaining the UUID for RLM Licensing

Without a valid PresenZ License, the writer node won’t output any file. To obtain a RLM license, you will need to communicate the UUID of the machine or the license server.

The process to retrieve the UUID varies depending on the operating system.


  1. Using Command Prompt - Open the Command Prompt. - Type the command:

    wmic csproduct get UUID
    • Press Enter. The UUID will be displayed.

  2. Using PowerShell - Open PowerShell. - Enter the command:

    Get-WmiObject Win32_ComputerSystemProduct | Select-Object -ExpandProperty UUID
    • The UUID will be displayed.


  1. Using Terminal - Open the Terminal. - Enter the command:

    sudo cat /sys/class/dmi/id/product_uuid
    • Enter your administrator password if prompted. The UUID will be displayed.


  • Ensure you have the necessary permissions on the machine to access this information.

  • The UUID is unique to each machine and is crucial for the licensing systems to identify and authorize hardware.

  • If there are issues or errors, make sure the system is updated and the commands are entered correctly.
