Burning a light path into texture bake?

Hey guys,

How can I bake a light path into geo?

Purpose being to highlight visible area in a camera view over a 800 frame shot; where the light hits the geo.

So the final output would be; an unwrapped texture that show's black background with a white path burnt into the BG.

I've seen this done before by another artist, where a light was linked to the moving camera, and somehow this burnt/baked in an area that show's the frame area. The light was set up with the the same ratio and size as the camera film back.

Thanks
Dave
