Description
Builds the mesh according to the current property
values. (The mesh construction properties specified
in the previous table have no effect until
is called.)
Generates a script error if any properties specify an
invalid list.
Generates a new normal for every vertex in every
triangle. The
style
each triangle is clearly delineated, or
method assumes that all triangles were specified in a
clockwise order.

Access Description
Get and set Lifetime of all particles emitted, in
milliseconds.
Get and set Color value of a particle at the end
of its life.
Get and set Color value of a particle at the start of its
life.
Get and set The variation of a particle's color
throughout its life. The change can be
based on either velocity or age.
Get and set The size of a particle at the start of its life. Positive integer.
