[SOLVED] I need some help W/ Leaks.

[bestiebest]

So, I was making a map. It was going fine, no errors to account for.

But later, something happens. I get a leak from a water tower prop. I move it about, and it doesn't fix it. Eventually, I get tired of it, and delete the prop.

That was the only leak.

And then, suddenly, another prop is said to be leaked. This prop had literally never been a problem up into this point.

So, why is this? Someone tell me, please.

Nevermind, answered my own question.

If your skybox is massivly large, then it causes a leak.

For no reason.

But whatever.

Anyone having this issue, here's your answer.

A leak is a gap in the level that leads to the void. Usually the closest entity (be it prop or whatever) reports the leak. Removing the entities that report it won't fix the problem (unless they're outside the level and literally in the void, the black area shown in hammer's 3d view).

You can locate the leak by going under the 'Map' tab on the top and selecting 'Load Pointfile', this shows a visual red line from the entity that reported the leak to the void. In order to "seal" the leak, you'll have to connect the brushes (world brushes, not entity brushes, they don't seal) to seal the level from the void. If you have a feeling there might be more possible leaks, you should check for them by compiling with VBSP only and without starting the game, then if the compile log reports
*** leaked ***, repeat the locating process.

Alternatively leaks can happen inside the level, if you're using areaportals and they aren't sealing off the room they're used in.
