Todo: What's the difference between this and material surface properties? This seems to be a leftover from materials.txt.

Bullet impacts on the car.

Material types are bullet impacts. To make a material use a particular material type, editscripts/surfaceproperties.txt (or scripts/surfaceproperties_mod.txt) file and set "gamematerial" to a string containing the letter shown below. For example, to make something metal:

"custom_surface"
{
	// ...

	"gamematerial"	"M"
}

Code:To add or change material types do the following:

• Find code file decals.h (found in \server\decals.h).
• To add, place #define CHAR_TEX_CUSTOMNAME '2' (any character).
• To change, find CHAR_TEX_UNUSED (or used) change it to CHAR_TEX_CUSTOMNAME 'R' (any character).
• Don't forget to modify the s_pImpactEffect array in fx_impact.cpp (found in \client\fx_impact.cpp).
