A Particle Emitter Property asset contains settings for particles created by a Particle Emitter.

Format
A Particle Emitter Property asset describes how a particle changes over its lifetime, such as its color, size, and velocity. Each of these properties are defined by an xParInterp struct:


 * val is an array of 2 floats. The 1st float is the start value of the interpolation, and the 2nd float is the end value.
 * interp is the interpolation mode, which determines how the current value of the interpolation is computed over time:
 * ConstA (0 or 0x48e48e7a) - Always the start value.
 * ConstB (1 or 0x48e48e7b) - Always the end value.
 * Random (2 or 0x0fe111bf) - A new random value between the start and end value, refreshed every freq seconds.
 * Linear (3 or 0xb7353b79) - A value between the start and end value, found by using linear interpolation.
 * Sine (4 or 0x0b326f01) - A value between the start and end value, found by using sine interpolation.
 * Cosine (5 or 0x498d7119) - A value between the start and end value, found by using cosine interpolation.
 * Time (unused, 6) - The current time of the interpolation.
 * Step (7 or 0x0b354bd4) - The start value until time*freq >= 0.5, then the end value.
 * freq is the frequency of the interpolation when using Random, Linear, or Step mode.
 * oofreq is the frequency of the interpolation when using Sine or Cosine mode.

The actual asset is defined by an xParEmitterPropsAsset struct, which inherits xBaseAsset (Object Asset):


 * parSysID is the ID of the Particle System that the Particle Emitter should use.
 * rate is how many times per second a particle is emitted.
 * life is the lifetime in seconds of a particle.
 * size_birth is the start size in units of a particle.
 * size_death is the end size in units of a particle.
 * color_birth is the start color of a particle (red, green, blue, and alpha).
 * color_death is the end color of a particle (red, green, blue, and alpha).
 * vel_scale is unknown/unused (all set to 0).
 * vel_angle is unknown/unused (all set to 0).
 * vel is unknown/unused (all set to 0).
 * emit_limit is always -1.
 * emit_limit_reset_time is unknown (usually set to 0 but sometimes not).

At the end of the xParEmitterPropsAsset is a list of Links.
