You can see through the top of a Block.

1. Build a Long 2*1 tunnel, like for Stripmining Underground.
2. Put your FoV Setting to Maximum/pro
3. Go into F5 mode, so you can see your character from behind.
4 Sprint along the tunnel and adjust you amera angel , so that it does not goes any higher , because of the ceiling.

Now you are able to see through the ceiling.
