ok i dont intend to release rebuilt official maps to the public. however i am just messing about with them to learn how they did things.

in avalanche there are a number of exploits or places where players get stuck. i want to fix those but there seem to be walls all through the map that i cant pass through when recompiled.

when i look through these walls i can see parts of the next section of map are not rendering, if i no clip past the wall, they render.

what are these zones?
what are they called so i can assign them the correct entity name again?

They're a variation of areaportals and hint brushes, meant for optimization.

ok so if i wernt to the entity to rename them..get that back working (or mostly working), what would i need to call them

trigger_hint

something_areaportal?

Hints are hints by their texture, not because they're tied to a function.

func_areaportal for areaportals.

My guess is you used vmex to decompile the map

It can mess up brushwork, so in hammer and game you will see brushes that just arent there in the original, also it doesnt handle areaportals and converts them back to brushes. If you get the effect of stuff rendering only when you go thru them it leaves you only 2 options really, delete them or rebuild them.

hmm yeh i see what u mean about the areaportals and all the hint brushes :)
