Remarks

This effector initializes the start value of a specific particle parameter (see property Parameter) for new particles. The start value is chosen from a given Distribution. If Distribution is , DefaultValue is used as the start value for all particles.

This effector acts like a standard StartValueEffectorT, except: The vector created by the Distribution or the DefaultValue is treated as a position given in the local coordinate space of the particle system. That means, the position start value moves with the particle system. If the ReferenceFrame of the particle system is World, the start value of each particle is multiplied with the poses of the particle system (and its parent particle systems) to convert the position from local space to world space. If the ReferenceFrame of the particle system is Local, the pose of the particle system is ignored.

Cloning: When an instance is of this class is cloned, the clone references the same Distribution. The Distribution is not cloned.
