Making See-Through Glass
As any young vandal will tell you there is nothing
more fun then smashing glass, so how do we make breakable glass in CS?
It's very easy actually, First of all go into
the texture browser and type GLASS in the FILTER and choose anyone of the
many glass textures. Then create the window where you want it.

Once you have positioned it make it an entity
(CTRL+T) and choose FUNC_BREAKABLE..
STRENGTH- About 50 takes a few bullets so work
it out from there.
MATERIAL TYPE- There are many types but the
default one is glass so leave it as that.
RENDER MODE- This makes it see-through, select
TEXTURE from the list.
FX AMOUNT- 0 is invisible and 255 is fully opaque
so about 90 is great for glass.
There you go have fun with smashing the glass!
