Hi there,
This is just a silly user error but I couldn't find an answer online.
No matter how large I make the render screen, the render itself does not increase in size. Is there a hotkey or menu setting for this?
Do you have Compositing nodes on? Maybe you have some resize node that is being piped through? Perhaps you have render region available?
That did the trick! I didn't realize I had a render region on... Thanks Omar!
