Hello - your environment looks correct to me, I think the display mode is not using it - it appears to be set to use a solid color - check the Display panel for ‘background’
Hello- does a full render do something different than the viewport display? If so I would check the Display panel setting. Feel free to post your file of course.
Thanks, between yesterday and today, I closed Rhino and had to open it again to test what you suggested… and just restarting Rhino seems to have fixed it. I now see the environment and reflections in the metal in the rendered view again.
