This is the list of physical surface types that Source recognises, as defined by the files referenced in <code>/scripts/surfaceproperties_manifest.txt</code>.
These are lists of physical surface types (<code>$surfaceprop</code>) that Source recognizes, as defined by the files referenced in <code>/scripts/surfaceproperties_manifest.txt</code>.


Surface types define the physical properties of an object including friction and density, collision/footstep sounds, the effect of bullet impacts and, if the object is destructible, health and [[gibs|gib]] type.
Surface types define the physical properties of an object including friction, density, collision/footstep sounds, the effect of bullet impacts and, if the object is destructible, health and [[gibs|gib]] type.


Both [[material]]s and [[model]]s define their surfaces with the [[$surfaceprop]] command.

Most of these surface properties are shipped with {{Hl2|1}}, and therefore can be found in every other game ever made.<br>
This table represents <code>scripts/surfaceproperties.txt</code>. Every game is shipped with this file and therefore every game has all these surface properties, with some exceptions.<br>
Surface properties containing a game logo in the "In" column have been added in those games (and mods of it, like {{portalrev|1}} being a mod of {{portal2|1}}). These surface properties are '''not''' in Half Life 2.<br>
Games listed in the "Not in" column had the surface property deleted for one reason or another.
Games listed in the "Not In" column had that surfaceprop removed. Such as "Zombieflesh" which was shipped with {{hl2|1}} but is ironically not in the {{l4ds|1}} anymore.


{{note|This list only contains surfaceprops from official valve games. Surface properties that were introduced in third party mods/games such as {{gmod|1}} and {{bms|1}} can be found [[Material_surface_properties#Third_Party_Games/mods|below]].<br>
Some games introcude their own surface properties, which can be seen [[#Game-specific|below]].
If a surfaceprop happens to also be in a third party mod, it will also be listed as "In" inside this list.}}
 
{{note|The following games have been checked for its surfaceprops: {{hl2series}}, {{l4ds}}, {{dods}}, {{asw}}, {{css}}, {{portalseries}}, {{tf2}}, {{infra}}, {{bms}}, {{gmod}}.<br>

== Game-specific ==
 
The following surface properties are not part of the base <code>scripts/surfaceproperties.txt</code> and therefore not available in every game.<br>
These lists only show the surfaceproperties that were added for that game. They still contain all the surfaceproperties in the above list, unless otherwise specified.
 
{{note|Various games are shipped with the <code>scripts/surfaceproperties_hl2.txt</code> from {{hl2|1}}. Some game's <code>scripts/surfaceproperties_manifest.txt</code> do not actually use these files though.<br>
These tables are set up to only show the surfaceproperties that are used according to their manifests.}}
 
=== {{hl2|4}} ===
These surfaceprops were introduced specifically for {{hl2|1}} and its episodes, but this file was shipped alongside numerous games.<br>

These are lists of physical surface types ($surfaceprop) that Source recognizes, as defined by the files referenced in /scripts/surfaceproperties_manifest.txt.

Surface types define the physical properties of an object including friction, density, collision/footstep sounds, the effect of bullet impacts and, if the object is destructible, health and gib type.

Both materials and models define their surfaces with the $surfaceprop command.

Note.pngNote:For GoldSrc GoldSrc, use sound/materials.txt. This file usually has documentation at the top dictating which surface types are available in the given mod.

Types

This table represents scripts/surfaceproperties.txt. Every game is shipped with this file and therefore every game has all these surface properties, with some exceptions.
Games listed in the "Not in" column had the surface property deleted for one reason or another.

Some games introcude their own surface properties, which can be seen below.

Note.pngNote:This list only contains surfaceprops from official valve games. Surface properties that were introduced in third party mods/games such as Garry's Mod and Black Mesa can be found further below.
If a surfaceprop happens to be missing in a third party mod, it will still be listed in the "Not in" column.
Note.pngNote:The following games have been checked for its surfaceprops: Half-Life 2Half-Life 2: DeathmatchHalf-Life 2: Lost CoastHalf-Life 2: Episode OneHalf-Life 2: Episode Two, Left 4 Dead seriesLeft 4 Dead series, Day of Defeat: Source, Alien Swarm, Counter-Strike: Source, Counter-Strike: Global Offensive, Portal series, Team Fortress 2, INFRA, Black Mesa, Garry's Mod, Titanfall, Titanfall 2, Postal III.
Todo: Check other games and add them to the list of checked games.

Special

 Description Not in
Default
Default_silent For invisible collision materials, like sky. Bullet impacts are neither visible nor audible, giving the illusion that there is no impact.
Floatingstandable This one is used for puzzles where we want something that floats but the player can stand on without it sinking beneath the water.
Item Small med kit, smaller tech items, battery.
Ladder Ladder is a fake material for walking on ladders. Titanfall Titanfall 2
Woodladder Same as Ladder, but with wooden climbing sounds.

Game-specific

The following surface properties are not part of the base scripts/surfaceproperties.txt and therefore not available in every game.
These lists only show the surfaceproperties that were added for that game. They still contain all the surfaceproperties in the above list, unless otherwise specified.

Note.pngNote:Various games are shipped with the scripts/surfaceproperties_hl2.txt from Half-Life 2. Some game's scripts/surfaceproperties_manifest.txt do not actually use these files though.
These tables are set up to only show the surfaceproperties that are used according to their manifests.
