Hi,
I have SceneA.max. Just a tea pot and a light. Rendering and IPR are fine.
I make SceneB.max. Just two tea pots and a light. I merged "Render Settings" from SceneA.max with File>Import>Merge.

Render Settings will be the same as SceneA.max, of course. But Rendering and IPR doesn't start.
Reset from File menu, But GPU renderer dosn't start at all. Reset Settings also doesn't help. I have to reboot 3dsMax.
Share the scene files; open SceneB.max and merge the settings in SceneA.max. Does it work correctly?
