Changing to Redshift from code is straightforward and works fine. But, if you change to Redshift manually in the render settings dialog, C4D also changes its menus - the Redshift menu appears in the main menu and there are changes in the Window and Create menus, and possibly others.
When changing to Redshift programatically this doesn't happen, the menus are unchanged. Is there a way to force the menu update in Cinema? I've tried using EventAdd() but it doesn't help. It's a bit disconcerting for users to see that Redshift is being used to render but they can't access the Redshift RenderView window, for example. The only way is to manually change back to the standard renderer and then switch to Redshift manually.
I wondered if this is possible or just something users will have to live with.
