I am trying to put the sample helicopter in my map but i don't have a func glass in my editor... is this normal?? Also I am trying to get the glass like in hos3 where just small pieces break off and it takes a while to shoot all of the glass out..... if you can help or know how to do what i'm trying to do please help me... thnx

A different entity was used for glass in singleplayer if I recall correctly. I know the code sure is different  

I changed all of the func_glass to func_breakable_brush and this worked for the helicopter. But the type of glass i want is the glass that you have to shoot a bunch of times and little pieces dissapear until you are able to fit through the window....  I tried changing the material key/value but I cannot seem to find the material that does that cool thing with the glass.... some help please...

It was my understanding that func_glass was automatically of the type you describe in Single Player, and was of the "all break at once" type when in Multiplayer.

You don't need to have a funtion glass to do what you want in SP. just look for the texture "glass1" . Sorry but I don't remember the texture folder right off the top of my head. Use it in a thin brush, this will break up into small pieces when shot or you can use the secondary fire on the pistol to break out the whole pane. I hope this is what you are looking for.

O.K. I got it working for the most part... glass_spread in the common folder was the one i was looking for. It works fine except when I put the window in the spot I cut out of my wall, it does not show up in the game until i shoot it and then it looks like there is a leak or something going on... but there is no leak in my map I only get this when I put the window in it's "frame"... I tried caulking the brush and putting the texture on both sides but that did not work either... oh i'm so close here but still having trouble....

If it looks like there's a leak, then the vis doesn't think you should be able to see through it.  Sounds like you haven't made it func_glass, so the engine thinks the brush should block the vis, and when you shoot the texture so you can see through it, the engine isn't drawing whatever's on the other side.

Had same problem with that same texture. Not sure of the reaon. Tried all kinds of things. finally got home and had a look at the texture folders. Try glass1 in the shop texure folders. This works without hassels. Just build your brush with this texture and your done.
