im like stomped I see so many colors but i dunno which one is the leak.

I take it you know how to load it up in the game? Something I find helpful. I have a lot of entities and they're spread around a lot. When you compile it will tell you where the nearest entity is that see's the outside world. Start at that entity and follow the yellow brick road so to speak hehe.

Also, another thing i find helpful is to make a really big brush and cover a big chunk of your map with it. compile and see if you have the leak. If you still have the leak then it's in the part of the map not covered. You can narrow down where the leak is at this way.

Hope it helps :)

ok, or you could compile the map if you have 3.5, then go to map-->Load pointfile. Then load the .pts with the name of your map. In your 3d view you'll see a whole bunch of lines. Ignore most of them, and joust look for one that goes in between 2 brushes. This should give you idea.(reason why i say ignore most of them, is because they go everywhere and even through a perfectly fine brush. But is saves time becaue you dont have to compile and run game, then go back for multiple leaks).

Also, just put -particles 99999 in your 'additional game peramiters' for more particles in the in-game pointfile.

If you do use Hammer v3.5, the line should turn RED where the leak is, it did for me.

blah it worked I used the .lin and I have has 3.5 for like 2 months
