Basically my issue appears to be that when a corner isn’t visible by the edge of the camera, the camera doesn’t render the Ambient Occlusion that that corner would have otherwise provided. It’s as if the AO is only applied to the camera and not to the actual objects… It’s incredibly noticeable especially when you’re at a perpendicular corner and move the camera up and down. Is there any way to make it so the AO stays where it should be even when the camera isn’t looking directly at the corner that’s outputting the AO?
This GIF shows what I mean. If you see the top corners of the wall, when those corners aren’t visible, the AO also is removed gradually as the camera stops focusing on the corners.
