Hi
I know about visleafs hint/skip textures in terms of optimising and i understand the general application of the areaportal brush and setting its class to func_area portal. I have made small test maps will multiple rooms only and use areaportals in the doorways to understand it, but when it comes to using them outside in the open, i get a bit confused.
When i decompiled granary, i saw moderate use of areaportals but couldnt understand how the portals were behaving since the portals seemed to leak but were ok (if they did infact leak, this would be a problem)
Like i explained, inside buildings / closed spaces im fine with them, but closed spaces connecting to outside areas is where i get confused. I have used the following as referance, and have read the Valve dev community wiki too.
http://optimization.interlopers.net/index.php?chapter=areaportals
Also, if possible occulation would be good to know, but not important since Areaportals are generally used instead of occulation apart from RARE occasions when areaportals cannot be used.
Cheers
