PresetName
From Data Realms Wiki
The PresetName is the name that identifies an object. For example, a guns PresetName may be "Assault Rifle", so whenever the weapon is shown in-game it will be called "Assault Rifle".
In modding, lets say for the weapon above, it would be as follows:
AddDevice = HDFirearm PresetName = Assault Rile Description = Decent gun with moderate rate of fire and damage.
As you can see, the device is a weapon, and its name is 'Assault Rifle'.
