$burning


... 

$burning
is a material shader parameter available in the and
. 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%.
