Render Region not always rendering the correct size or seems to move your render selection once you hit render.
Hello Plang99,
Could you please make sure that your aspect ratio in the scene stays the same when you are rendering?
This happened to me when I was setup using studios, I was using a different camera in the live viewer than was linked in my studio, so the focal length was different and gave a different perspective. Just one more thing to check on.
I'd check to see if what Matt mentioned was the case. I've accidentally done this myself.
