Hi

That's a scene-specific problem with some nodes.

Do you have these four nodes in the scene?

- defaultArnoldRenderOptions
- defaultArnoldDriver
- defaultArnoldFilter
- defaultArnoldDisplayDriver

You can check in the Outliner, just clear Display > DAG Objects Only

If so, then try this:

- close the Render Settings dialog
- delete those four nodes
- save the scene (with a new name)
- restart Maya
- load the scene you just saved

Thank you!  That's the first solution that I've tried after many that works.  Next beer's on me 😉
