When you re-render a frame mental ray automatically tints the view slightly making it a little darker just before the buckets start rendering so that you can see what is updating in the frame buffer, but is there a way to turn this feature off? I want to see the untinted previous render get updated with the new so I can more clearly see the difference.
Also, in Brazil you could set the render order to custom and drag your mouse around the render window to only render certain parts of the frame, is there a way to do something similar in mental ray? I only see the typical options like Top to Bottom, Left to Right etc.
Thanks in advance for any help!
