Bullet Penetration in Day of Defeat: Source
Just like Bullet Penetration in Counter-Strike:Source, this article aims to answer all the questions map makers might have about bullet penetration in Day of Defeat:Source.
Setup
The way I set this test up was to create a map with 80 walls, each 1 unit bigger then the last. I then went through and found out which exact wall size stopped a bullet from the variable gun. If you want a copy of my test map,
download here. To run the tests yourself, download that map, add whatever player_start entity you need and run the map. When you shoot the glass, if you bullet goes through then that means its wallable. To change the material for the glass, do not replace the glass texture! A much much eaiser way is to goto surfaceproperties.txt and change the glass's material to whatever you want. The character's are listed below.
Results

| Thompson | 22 | 6 | 3 | 6 | 29 |
| Mp44 | 27 | 8 | 4 | 8 | 40 |
| Bar | 46 | 13 | 7 | 13 | 67 |
| K98 | 80+ | 23 | 11 | 23 | 80 |
| Garand | 55 | 15 | 8 | 15 | 73 |
| K98 Scoped | 80 | 30 | 15 | 30 | 80 |
| Springfield | 80 | 30 | 15 | 30 | 80 |
| Mg42 | 71 | 20 | 10 | 20 | 80 |
| 30cal | 71 | 20 | 10 | 20 | 80 |
| C96 | 22 | 6 | 3 | 6 | 29 |
| Carbine | 21 | 6 | 3 | 6 | 29 |
As you can see from the data, most objects have very little penetration to them. Even wood, which should be atleast half as penetrable as glass.
Dependance on outside files
The penetration values for certain materials can be changed. In the weapon files there is a property called 'Penetration,' this does absolutly nothing. In the surfaceproperties, the only way to change a material's penetration value is to change the material type. Just as it was said in Bullet Penetration in Counter-Strike:Source. Density only seems to change the type of bullet hole you draw when you shoot.
If you are a mod maker and you want to change weapon penetration without changing the material type, the only way to get this done is to modify the day of defeat:source dll with a simple hex editor. Data offests will be posted soon for the values of gun penetration.
