FBuoyancyOrganic

All of the FBuoyancy settings control the buoyancy (how fast or slow an object will sink when dropped in a pool of water) of some type of material in the game. A setting of -1.000 means the material will sink immediately to the bottom of the water. A setting of 0.000 means the material will slowly settle into a mid-level height in the water. A setting of +1.000 means the material will float on top of the water. Other values control the speed at which the material will sink and the height at which it floats.

The FBuoyancyOrganic setting controls the floatation mechanics of "organic" materials. Any animal-based matter is classified as organic. So, this will set how the corpses of slaughterfish or mythic dawn assassins will sink or float.
