Thanks, that’s a big help. I was already aware that getting ‘_cameraRequiresSetup’ flag set was the critical piece - thst’s actually why I was trying detach() + attach() since that *should* set _cameraRequiresSetup to true. But your point about getting the correct RenderStage makes a lot of sense, and might explain the strange things I see indeed. > > PS.

I might do that, but it can wait - thank again for your help. Kind regards, James
