warning.png This reference page was created for Arma 3 v1.60+, some fields may not exist in prior games and versions.



Integer: Determines the manipulability of the class.

Value Type Description
0 ReadAndWrite Additional values can be added
1 ReadAndCreate Only adding new class members is allowed
2 ReadOnly No modifications enabled
3 ReadOnlyVerified No modifications enabled

All BIS classes are ReadOnlyVerified and can only be inherited into a new class

access = 2; //ReadOnly


Introduced with Arma 3 version 1.60

Integer: Allows restricting the AI from entering prone with two levels of emphasis

Value Description
0 No change in behavior
1 Less preference for going prone
2 Almost never going prone



String: Points to a corresponding CfgSurfaceCharacters entry, which defines the clutter on this surface.

character = "Empty";		//No clutter will be used on this surface
character = "SeabedClutter";	//SeabedClutter defined in CfgSurfaceCharacters will be used on this surface



Float: Amount of dust vehicles will create on this surface (higher value = more dust)

dust = 0.75;	//High amount of dust, used for GdtStratisDryGrass
dust = 0.05;	//Almost no dust, used for GdtConcrete



String: Defines which ground texture and roadway texture filenames this surface will apply to

files = "gdt_grass_green_*";	//Tells the ground texture what surface it corresponds to
files = "surfint_wood_*";	//Tells the texture used in the roadway LOD what surface it corresponds to

From commented configs of BI (binarize\bin)

Caution: wildcard pattern "files" is matched using special purpose matching

* may be used only as last character of the pattern
* matches any string in filename
? matches any single character in filename

when six trailing question-marks are detected "??????", two patterns are matched:
full pattern and short pattern with ?????? omitted


Float: Unknown

friction = 0.9;	//Default value, used by all A3 surfaces



Float: Used to simulate grass cover at a distance by sinking the target into the ground (higher value = more sinking)

grassCover = 0;		//Used by GdtStratisConcrete, there will be no simulated grass cover at a distance
grassCover = 0.05;	//Used by GdtStratisGreenGrass, there will be some simulated grass cover at a distance



String: Defines what particle effect is shown when the surface is hit by a bullet, points to a corresponding entry in CfgAmmo

impact = "hitGroundHard";	//Used by GdtStony, particle effect will be chunks of rock flying when hit
impact = "hitGroundSoft";	//Used by GdtStratisDirt, particle effect will be dirt flying when hit

Integer: Declares whether the surface is water

isWater = 1;	//Used by SurfWater, declares the surface as water
isWater = 0;	//Used by Default, declares the surface is not water



Float: Unknown

lucidity = 0.3;	//Used by GdtStratisConcrete
lucidity = 3.5;	//Used by GdtStratisForestPine
lucidity = 150;	//Used by GdtStratisSeabed



Float: Defines the maximal coefficient of difference between the color of the surface and clutter (must be greater than or equal to 1)

maxClutterColoringCoef = 1.35;	//Used by GdtStratisConcrete
maxClutterColoringCoef = 1.5;	//Used by GdtBeach


Float: Defines the maximum speed coefficient on that surface

maxSpeedCoef = 1;	//Used by GdtStratisConcrete, no change in speed
maxSpeedCoef = 0.9;	//Used by GdtStratisGreenGrass, 10% reduction in speed
maxSpeedCoef = 0.8;	//Used by GdtStratisForestPine, 20% reduction in speed




restitution= 0;	//Used by every surface


Float:Defines the roughness of the surface when driving over it in a vehicle (higher value = more bumps)

rough = 0.05;	//Used by GdtStratisConcrete, minimal bumps
rough = 0.15;	//Used by GdtMud, fairly bumpy



String:Defines the sound played when walking or driving a vehicle on the surface, points to sounds defined in SoundEnvironExt

soundEnviron = "drygrass";	//Used by GdtGrassDry, dry grass sound
soundEnviron = "gravel";		//Used by SurfRoadDirt, gravel sound
soundEnviron = "int_wood";	//Used by SurfIntWood, weapons fired while on this surface will have a reverb effect.

This value also determines the sound for footsteps inside of a building corresponding for the roadway LOD. It is important to use corresponding textures for surfaces that are indoors or outdoors, as it has an effect on the sound when firing weapons on that surface.

String:Defines the sound played when the surface is struck by a bullet

soundHit = "concrete";		//Used by GdtStratisConcrete, sound of bullet hitting concrete is played when this surface is hit
soundHit = "soft_ground";	//Used by GdtStratisDirt, sound of dirt is played when this surface is hit

Float: Defines the surface friction on this surface (lower value = more friction)

surfaceFriction = 2.5;	//Used by SurfRoadTarmac, highest surface friction value
surfaceFriction = 2;	//Used by SurfRoadConcrete, above average surface friction value
surfaceFriction = 1.8;	//Used by GdtDirt, below average surface friction value
surfaceFriction = 1.5;	//Used by GdtMarsh, low end of surface friction values



Integer: Defines the alpha value of vehicle tracks

tracksAlpha = 1;		//Default value used by all surfaces


Integer: Unknown

transparency = -1;	//Default value used by all surfaces
