How do I set Arnold in the USD Exporter with MaxScript?

[ckalcevi]

I am trying to export all objects in my scene to their own seperate USD file, but I don't see an option to enable the Arnold Plug-In in the maxscript documentation.

Any help would be appreciated.

You can set the Arnold Plugin-in configuration with .ContextNames, the context to specify is "MAXtoAContext"

https://help.autodesk.com/view/MAXDEV/2025/ENU/?guid=MAXScript_USD_UsdExporter_html

  .ContextNames : string array : Read|Write

A list of contexts to apply on export. A "context" is a customization created using the 3ds Max USD SDK that sets export options, including specifying chasers and chaser arguments. In the UI available contexts appear under "Plugin Configuration".

Thank you! Just for curiosity sake, how would I get a list other avaible plug ins? Like vray or redshift? Is there a maxscript command?

You can get the list with this python command: maxUsd.JobContextRegistry.ListJobContexts()
