Greetings all.
I eyeballed through the forum and didn't find anything helpful.
My problem is this: I've created a map to learn Hammer and it's turned out really well for my first map since Duke3D, except for one thing.
While the map plays fine, all the walls and floor burshes are allowing Bullets to pass through. Like the common wood crate. Not breaking, but you can still get hit on the other side. This means that you can fire from one room into the next. Not good. And the really sad part is that just about ALL the guns are shooting through.
Now, I've had some suggestions from some of the other mapping sites, (I setup a small test range in the "backyard" of the map to try out the solutions I was given.), and none of them work.
Double walls (touching) allow the bullet to pass.
Double walls (with a gap inbetween) and the bullet passes BOTH.
Double wall with one wall textured with No bullet - BULLETS FIRE THOUGH BOTH WALLS.
Single wall with increased thickness - I end up with a wall like 15 feet thick before the bullets stop passing though it entirely. (Even a little damage passing though is not ok) Huge walls should not be the answer - because Valves maps have thinner walls than what I'm using and they don't pass bullets.
I've tried a great variety of textures to see if perhaps the textures I chose are the problem, but it seems the choice of texture doesn't play a role in ballistics, in the manner I need.
Is there a way to tag brushes, say, with an entity that makes them bulletproof (I.E. you can't shoot though it)?
Or perhaps there is a variable on the brushes themselves I can't find?
Please, help me out. This is frustrating me knowing I've got a good map aside from this problem.
