Ok. So they were still using the basic quake3 tool chain, just that they
based the PVS off of manually place portals and something that I assume is
like the flood fill zone assignment Tom Forsyth mentioned. It wasn't
particularly tight fitting PVS, but it did work better on the indoor/outdoor
combination than q3 vis.exe, and thier baseline hardware was T&L so they
weren't all that worried about sending extra geometry.
