Applying Filters to Particle Systems
Filters can only be applied to a particle system’s emitter. You cannot apply separate filters
to individual cells. (Filters can be applied to the source of a particle cell, but not to a cell
directly.) As a result, filters affect the entire particle system, including every element in
the pattern.
