Glossary

*Property*	*Function*
Separate Axes	Control the particle size independently on each axis.
Size	A curve defining the particle’s size over a speed range.
Speed Range	The low and high ends of the speed range to which the size curve is mapped (speeds outside the range will map to the end points of the curve).
