I like the “Render Region” concept from the tutorials. I have setup a render that looks fine in the Render view, but when I go to the Scene view, and I've got the correct camera selected, I draw the “Render Region” rectangle, press render, and nothing happens. Any ideas? Follow up: Why can't I use the “region” approach with the Render View itself?


Side question: I want to decrease the render resolution to speed up renders. My camera is at 1280x720. I edit the Mantra Node and click “Controls”, choose “1/4 resolution”, and press Render, but the resolution is not decreased. The only way I seem to be able to decrease resolution is to set it on the camera itself. What am I doing wrong?
