No more environment variables! You can use the Arnold License Manager to configure licensing for Arnold:
- Just sign in to activate a single-user Arnold license
- Connect to one or more network license servers
- Switch between different licensing systems (single user, NLM, RLM)
Whatever you set up in the Arnold License Manager is used by Arnold when you render.

If you're not running a 3d application (for example, you're setting up a render node), then you can run the ArnoldLicenseManager executable.
- MtoA: Look in the bin folder of the MtoA installation. For example, C:\Program Files\Autodesk\Arnold\maya2019-4.0.1\bin\ArnoldLicenseManager.exe
- C4DtoA: Look in the arnold/bin folder
- C:\Program Files\MAXON\Cinema 4D R20\plugins\C4DtoA\arnold\bin\ArnoldLicenseManager.exe
- /Applications/MAXON/Cinema 4D R20/arnold/bin/ArnoldLicenseManager
- HtoA: Look in the scripts/bin folder
- KtoA: Look in the bin folder of the KtoA installation
- MAXtoA: Look in the MAXtoA install folder. For example:
- C:\ProgramData\Autodesk\ApplicationPlugins\MAXtoA_2020\ArnoldLicenseManager.exe
How does it work?
If you really want to know how it works, here's how:
- The Arnold License Manager saves a a plain-text config file on your system.
- This config file is specific to your user account.
- When you render, Arnold reads this config file and uses that information to get a license.
The config file
The Arnold License Manager is a user interface for setting up this config file.

{ "license": { "clm": { "servers": [ "@localhost" ] }, "order": [ "network" ], "rlm": { "servers": [ "5053@localhost" ] } }, "version": "1.0" } |
The config file is a per-user setting:
- Windows: %LOCALAPPDATA%\Autodesk\Arnold\
- Mac: $HOME/Library/Preferences/Autodesk/Arnold/
- Linux: $HOME/.config/Autodesk/Arnold/
When Arnold renders a frame, Arnold reads the config file to get the license server connection information.
