Q100096: Getting Started with Modo CL



This article will help you set up and start using Modo CL, a command line version of Modo.


Modo CL is a headless (no GUI) instance of the application.

The advantages of this are as follows:

  • Reduced memory usage
  • No license requirement
  • Assists integration with Render Farms


Launching Modo CL:

Modo CL can be launched through the Terminal or Command Prompt. The default locations for launching Modo CL are:



For Modo 11.1v1 and below:

 "C:\Program Files\Luxology\modo\[version]\modo_cl.exe"

For Modo 11.2v1 to 16.0v4:

"C:\Program Files\Foundry\Modo\[version]\modo_cl.exe"

For Modo 16.1v1 onward:

"C:\Program Files\Modo[version]\modo\modo_cl.exe"






Navigate to where you installed Modo and type:



Executing and Querying Commands:

Commands can be queried in the main Modo application through the Command History. Every time a tool or feature is used in Modo, the equivalent command will be displayed here under the Undos tab. The command history can be accessed by pressing "F5" on the keyboard, or by clicking and dragging on the partition between the command bar and the item properties form.

Alternatively, you can look up every command under the Commands tab of the Command History:

Example Commands:

The following commands will; enable console output, open a scene, change the render frame range, render the scene and quit the app: 

log.toConsole true
log.toConsoleRolling true
scene.open "path/path/scene.lxo"
@ChangeRenderFrameRange.pl 1 10 1
render.animation "path/path/renderName" PNG

PLEASE NOTE: The paths will need to be amended to match your environment. You can change the frame range (format: <first> <last> <stepsize>) and the file type if desired:

  • JPG
  • $Targa
  • TIF
  • TIF16
  • openexr
  • openexr_32


Launching from a File:

You can pass a list of commands from a file which will then be run on launch. Modo will automatically quit after executing the command file. For example:

  • Save a file with the desired commands listed within as "commands.txt"
  • Launch Modo CL with the addition of '< commands.txt'
modo_cl.exe < commands.txt
modo_cl < commands.txt
