PTS

PoRTal File

A proprietary format used by the Valve Hammer Editor to point out leaks. It stores a line or series of lines that can be followed to find the location of a leak.

Created during the vbsp process only if a leak is present, it begins at an entity close to the leak and the follows the raytracing steps it took to find its way into void. Often not straight and meandering it may take some precise following to find the area where the leak is present, it is more a line threaded through the leak rather than a line that points directly to it.

If multiple leaks are present only one will be found and documented, it may take multiple .prt files to find all leaks in a map. Hammer can automatically, and most likeley will, load the only relevant .prt file to this map and this compile. A map's or compile's .prt file is useless to any other map or compile.
