Seamshot Calculator
Ray collision detection with brushes in Source-based games have a bug
allowing you to shoot through some of the seams. We call them seamshots
(more info on that here.)
This little tool of mine was created to find these seams in any given
Portal 2 BSP map, and give you a list of sar_drawline
commands
in a config file which you can execute in game to see all of the seams.
False positives are undoubtedly certain, and colors make absolutely no sense,
but it's enough for me so heck it, releasing the tool so maybe someone else
can fix it for me lol.
