Environment looks fine in rendered preview mode, but completely black in final render? My environment and render settings all seem normal, and when I go into rendered mode(Shift+Z or preview mode dropdown menu) it looks fine and lights the scene normally, but when I do a test render of the final frame, the environment disappears and doesn't light the scene or show up in reflections. I thought it might be my compositing setup somehow, but it looks like that while it's still doing the initial render, and I tried just plugging the rendered image into the final image slot to test it and it still looks the same.
