Add Bullet Damage to Buildings

Cut this geometry out of existing building models to create a nice war-torn look. Feel free to copy, scale, rotate, or add your own geometry for an even more damaged and chaotic look.

Only push the bottom chaotic geometry into the building. Scale the Z to increase or decrease the depth of the damage (before the boolean of course)

Note: Netfabb doesn't seem to be working at the moment, so I recommend sending the mesh through netfabb before you boolean.
