This page provides information on the Ambient Occlusion Render Element.
The Ambient Occlusion Render Element renders the entire scene with one texture mapped onto all objects in the scene. The resulting element can be used in compositing to control ambient occlusion separately.
While you can obtain a result similar to the Ambient Occlusion render element by applying the same texture to all objects in the scene and rendering as usual, such an approach requires additional time spent on reverting to actual materials, saving different versions of the scene, etc. The Ambient Occlusion render element provides you with a quick and easy way to render the scene with a single texture without the extra work.
