How do I reset render content conflict / enable pop-up box when I import from another rhino file

When I import/ insert another rhino file, it will import directly without showing the “render content conflict” pop-up for materials and generated new materials: Material [Imported]

Where can I reset and enable the pop-up?

Thanks

Hello - run the command RenderImportConflictOption and choose ‘UseDialogtoAsk’

-Pascal

It says unknown command. Is this command for a newer version of rhino? My rhino is in version 6 SR17.

That is a Rhino 7 feature.

You may want to update since you’re trailing 17 service releases behind, latest one is 6 SR 34.
