Breakable Glass

1. Create a brush where you want the glass to be, using the nodraw texture. Like real glass, it should be very thin (No more than 3 units thick under normal curcumstances).
2. Apply a nice-looking glass texture to one face (not on both sides). Make sure you use glass/glasswindowbreak070a. Don’t use glass/glasswindowbreak070b. All other faces should be textured with tools/toolsnodraw.
3. Select the brush and click the "Entity" button in the object toolbar. Choose func_breakable_surf in the drop-down list. (If you want the glass to completely shatter all at once, choose func_breakable instead.)
4. Go to the Material Type keyvalue and select Glass.
5. Add an env_cubemap to the surface of the glass texture.

 Note: You can apply your texture to just one side of the brush entity by opening the Hammer Face Edit Dialog, ensuring the Mode is set to Select or Lift + Select, and clicking once in the 3D view on the face you want to apply the texture to. Then, select a material with either the drop down box or the browse button, and click apply.
