Stitch Multiple Camera to one view.

Hello,

I have a video wall that contains 9 screens. I want to know how can I create 9 cameras in-game next to each other and have one camera to display the stitched view of 9 cameras? Can I use Ndisplay to merge multiple cameras into one camera view? Also, it needs to be running on one machine only. The video wall processor will stretch the image to a 9 screens and display it properly. i have uploaded the merged view of the 9 cameras and a stretched version of the same image.
