alt Hacker NewsUnreal supports Panini out of the box, but very few games seem to actually use it or any other alternative projection.

HYPER DEMON may be the best known and most extreme exception, it renders 180 degrees in front of you, then renders 180 degrees behind you as a red-tinted overlay, giving full 360 degree awareness if you can wrap your brain around it.
Weird that UE also implements this as purely postprocessing filter. Surely there is more efficient way to render directly using panini projection, or at least something closer to it? Could you do it in vertex shader or something
