Thank you, I will try that. My scene is rectangle actually... 1024x768 actually. My laptop is tied up with a render. I'm rendering this scene using the import background because I need to get it done. But I will revisit it again once the render is done and try your method. Thank you for the detailed walk through :) I'll let you know how it goes.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
