What does Render Region do?

[reyloads]

In the Frame Buffer, next to the Track Mouse While Rendering icon, there is a teapot icon called Render Region. What does it do besides draw a red box on the window?

Thanks a lot!

It defines the area, which will be rendered.
Just hit the render Icon (either in the toolbar or in the Frame Buffer) to see the result, after you placed the red square.
Very usefull to speed up the Rendering. With this tool you can easily focus on problem areas.

Thanks a lot. I had always wondered what the next step was.
