TYPE: POP
TITLE: Split POP

The Split POP births particles from other particles. It is a generator
POP.  Local variables are usable in parameters denoted with a *.

Parameters:
    Activation        - Turns the POP on and off		/activate
    Source Group      - Subset of points to birth from
Source
    Emission Type     - Where to birth from
	From particle - Birth from particle position
        From instance - Birth from geometry instanced on particle
    Density Threshold - When birthing from metaballs, continue sampling
                        points until the summed density exceeds this
                        threshold			/threshold
    Density Minimum   - When birthing from metaballs, points with densities
                        less than or equal to this value are not used	/densitymin
    Use Metaball Density - Tells the POP to use the metaball density function
                        as a probability distribution for birthing particles
Birth
    *Birth Probability - How many particles to birth per source point	/probmin /probmax
    Birth Group       - Group to contain birthed points
    Preserve Group    - Add particles to group instead of clearing group first
    *Life Expectancy  - How long the particle will live in seconds	/life
    *Life Variance    - Variance of life expectancy in seconds		/lifevar
    Kill Original Particle - After birthing, kill original particle
 Attributes
    Inherit Attributes   - Which attributes to inherit from source
    Initial Velocity     - How to set the initial velocity	
    *Inherit Velocity    - How much of inherited velocity to use	/inheritvel
    *Velocity            - Used to set or add to velocity 		/velx /vely /velz
    *Variance            - Variance of set or added velocity		/varx /vary /varz
    Ellipsoid Distribution   - Distribute the velocities in a spheroid
                               of size determined by Variance, rather than
                               a cube.
    Use as Origin        - How to set the origin
    *Origin Index        - Index as used in origin		/originindex
