FAQ113: Launching Nuke in safe mode on Athera



This article shows how to​ launch Nuke, NukeX, NukeStudio in safe mode on Athera, for troubleshooting any issues that you may encounter.



When Nuke runs in safe mode it will not load any third party plugins or user customisations and only runs using the contents of the Nuke install directory.

It specifically prevents the loading of custom Python plugins and export presets on startup, and stops any scripts or plugins in ~/.nuke and $NUKE_PATH locations from being executed. OFX plugins are also prevented from being loaded (including FurnaceCore).

Nuke's safe mode can help determine if any problems you encounter are caused by user customisations and/or third party plug-ins or if they happen with the core Nuke application.


Nuke in safe mode on Athera

To launch Nuke/NukeX/NukeStudio in safe mode on Athera you need to add the --safe flag to your Nuke Run Parameters dialog. This can be done by using the 'Edit Run Parameters' option under your Nuke session launcher. 

This is a list of steps illustrating the process for adding safe mode to a Nuke session:

1) Click the Apps tab or the Athera logo in the dashboard.

2) Click the settings menu next to 'Launch' under your Nuke entitlement 


3) In the Nuke Run Parameters dialog under 'Arguments', type --safe


4) Click Continue to save the argument as a run parameter Nuke can use for new sessions. 

Now, when you launch Nuke from your Apps section as usual, the Run Parameters will remain applied and allow you to run in safe mode.

NOTE: It is important to note that any future sessions of Nuke will launch with this parameter applied, until it is removed from the Nuke Run Parameters dialog above.

Applying this parameter to Nuke does not apply it to NukeX and Nuke Studio, the flag needs to be added individually for each application you're trying to test in safe mode. 



If launching Nuke in safe mode resolves your issue, this would indicate that the problem is likely caused by a third party plugin or Python script that you may be using.

We would recommend that you remove all plugins and customisations and reintroduce them one by one until you encounter the issue again. This will enable you to determine what is causing the problem.

Launching Nuke in verbose mode will output a list of all the custom plugins and scripts Nuke is loading, which may potentially be causing the issue. For more information on this, please refer to the FAQ114: Launching Nuke in verbose mode on Athera and troubleshooting potentially problematic plugins article.
