Working With Particles
Modifying an emitter’s other transformation parameters (Rotation, Scale, Shear, and
Anchor Point) changes the distribution of particles from that emitter and transforms
each individual particle. For example, if you create an emitter, then modify its Shear
parameter, the distribution of the emitted particles changes to reflect the new plane of
the emitter, and the particles are sheared along the same plane.
Blending
Any changes you make to the opacity or blend mode parameters for an emitter are
applied to the particle system as a whole—the result of the emitter is blended into the
scene. Within the emitter, the particles can be blended additively or normally (using
the Additive Blend checkbox). For more information about blend modes, see “
” on page 249. For more information about the Preserve Opacity setting,
Mask and Drop Shadows
Masks and drop shadows can be applied to particle systems. When the Drop Shadow
parameter is enabled for the source object (in the Properties tab in the Inspector), each
generated particle appears with a drop shadow. For more information on working with
drop shadows, see “
