$burning

$burning is a material shader parameter available in the Left 4 Dead series. It covers the $basetexture with a $burndetailtexture, to give the illusion that the model has been injured by fire. It does this by switching the clean version of the texture to a different .vmt with a "_burning" prefix, which slowly increases the opacity of the $burndetailtexture up to 100%.
