Part of map disappearing }Solved>

[X-20]

Well here is my first major problem in months.

So whats happening to me right now is i have a outdoor area, brushwork is clean, nothing overlaps, and the walls (except for the vishull) is detail, and radiant gives me no errors when i build.

But for no apparent reason, the entire area is void when its ingame, the brushes are all still there and etc though.

I have tried re-texturing everything.
I have tried scrapping some the brushwork and rebuilding it.
I have made sure my vishull is not detail or that the walls are shaders (except for the skybox)

And yes, i searched.

Thanks for any help in advance.

could the brushes possibly be off grid? ctrl+g will snap brushes to grid.

If you have, say, two rooms, and in one room, you have a spawn entity and the other is empty;

Code Select Expand

|====================|    |====================|
|                    |    |                    |
|                    |====|                    |
|                           info_player_start  |
|                    |====|                    |
|                    |    |                    |
|====================|    |====================|

And you place a structural brush in between the two rooms like such;

Code Select Expand

|====================|    |====================|
|                    |    |                    |
|                    |====|                    |
|                       +   info_player_start  |
|                    |====|                    |
|                    |    |                    |
|====================|    |====================|

+ = Structural brush.

Then the room without any entities in it will not be compiled.

Ah, that solved it, thanks.
