Styrofoam-Like Objects

I need suggestions. What should i do to make objects breakable when shot, but only the spot where shot? I want to make it so that i can make a table where if i shoot it, there will be a hole through it, not just a bullethole mark. I want the whole entire object shoot-up-able. i want it to be so that i can shoot a table leg off and the table will fall....

I've tried making a table out of breakable brushes, but when i shoot a part, theres not effect or anything. The little part i shoot just disappears.

Thanks.

Models are what you see that break into pieces (like those boxes you
toss around). Unless you model the only way is to build it out of
brushes....or code.

I'm sorry but this isn't possible. A brush cannot be see through on
just one specific place, and if it could, it wouldn't look realistic.
It's simply too much work for a small thing that noone will notice.

But making the table fall down when you shoot of a leg is possible. If
you make a table that's completley made up of "func_physboxes" and
adjust the settings a bit, it could be done. But i don't think this is
a good idea.

When you are new to mapping you should try and focus on the realy
important parts like map layouts and objectives. Small unnoticable
things like bulletholes and table legs is not what makes a map good.

Try and get a small level done and see what people have to say about it, direct response is the best way to learn mapping.

And, about the table... i'd recommend you to just make a table model and see how it looks.

Maybe you could change the func_breakable_surf entity with code to work with materials other than glass... That would be pretty complicated tho.

This isn't exactly possible unless you're playing a game like red faction with GEO-MOD (Shoot a bazooka at the wall and it makes a hole).
