    I remixed Valve's 2fort map which uses area portals. When I did a fast compile and ran the map, there were a few area portals that were closed for some reason. Could someone tell me how to fix this and also what the purpose is for using area portals in mapping? Thanks.

    Areaportals serve two purposes. One is to artificially limit the Potentionally Visible Set to render less stuff by removing entire areas of the map. The other is to perform a second culling pass after PVS by culling using the frustrum of the areaportal brush.
