Material surface properties

This is the list of physical surface types that Source recognises, as defined by the files referenced in \scripts\surfaceproperties_manifest.txt.

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 gib type.

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