It's not always the case that layers == nodes, but where possible, LOPs will record a node's id to the "HoudiniPrimEditorNodes". This custom data is set per-primitive, and you can see it in the Scene Graph Details.

You can get at the nodes with a help function we have in loputils, by passing a lop node and prim path to loputils.getEditorNodes(). It just helps get node paths from the node ids stored as customdata.

This is used in the Scene Graph Tree's "Jump to Existing Editor Nodes" option, when you RMB on a prim.

Hope this helps!

It's also worth mentioning, you may need to reach out to the Arnold team for help getting this properly configured, if it's not a husk-relate configuration issue.

Huh, that's really strange; perhaps the Arnold USD plugin is somehow not setup correctly? That error message Can't find Hydra plugin 'Arnold'. suggests that while HtoA might be setup, somehow the USD-side of Arnold isn't? Does this VM have a GUI? And if you can launch Houdini through it, do you get any other clues, when trying to use Arnold in Solaris?

I'm also surprised that it says Karma XPU is also unsupported...

I'm not sure what else could be going wrong, but maybe log a bug with Support, and see if further help can come through that route. It may be some sort of a misconfiguration... and that's a safer place to share potentially sensitive info.
