*'''IS_WARM''' - allows characters with [[infravision]] to spot things made of this material without the use of their regular vision.

*'''USE_MATERIAL_ATTRIBUTES''' - ignores the character's natural, trained up values for stats affected by the limb and uses the material's stats instead (e.g. a player with 10 DEX changes his arm to ommel hair, which is an artificial material and therefore uses ommel hair's flexibility as the arm's DEX.) This bodyflag is on by default.
