this glitch allows you to see inside a wall and x-ray for caves

when you are in f5 mode and walk in a 2 high tunnel it bounces like you would while walking

but when you bounce it does not push the camera outside like it normally does but it shows you inside the wall its simple to make thats why i think this is a glitch not so important but to put attention

sorry if you didnt understand the explanation but here is a picture if it helps
