The texture is just simply what gives the balcony the see-through appearance. In most games, pure black (RGB 255 255 255) is transparent, or see-through.

So, for you to fix this, you would need to:

1) Take the texture that covers the balcony, and strip it of black.
2) Take the map, and all of it's files, and open it in the SDK.
3) Take the balcony, which is just a square, and cut holes in between what would be the metal columns.'
4) Reapply the new texture, with real holes in the balcony.

All of this to simply be able to shoot through a balcony, you're better off doing this: eatthis:
