The Kill Height module is used to kill particles when they move above a defined height. It contains the following member(s):
A float distribution defining the height to kill particles at or above.
If true, the value will be considered as world-space values and remain unchanged when testing. If false, the height will be transformed to the world-space of the emitter.
If true, particles will be killed if they fall BELOW the height value. If false (the default), they will be killed when they rise ABOVE the height value.
Apply PSys Scale
If set to true, the sizes specified will take the emitter's scale into account.
If the 3D preview mode is enabled, a plane will be rendered at the height of the kill value.
