NOTE When a Particle Flow source icon is selected, all of its non-selected particles,
other than those shown as geometry, are colored white in the viewports. To see
all assigned particle colors, deselect the particle system.
Selected Choose how
selected particles on page 2833 appear in the viewports.
The choices are the same as for Type, above.
Force Operator
Particle View on page 2811 > Click a Force operator in an event or add a Force
operator to the particle system and then select it.
The Force operator lets you influence particle motion with one or more space
warps from the Forces category. Use this operator along with different forces
to simulate the effects of wind, gravity, and so on. The following force space
warps work with the Force operator:
■
Displace on page 2727
■ Drag on page 2706
■ Gravity on page 2721
■ Motor on page 2696
■ PBomb on page 2712
■ Push on page 2691
■ Vortex on page 2701
■ Wind on page 2724
NOTE By default, the influence of these space warps on Particle Flow particles is
equivalent to their influence on the 3ds Max 2 particle systems: PArray, Super
Spray, Blizzard, and PCloud. To obtain an influence on Particle Flow particles
equivalent to that of the 3ds Max 1 particle systems Snow and Spray, set
Influence
on page 2949 to 100.0.
TIP To make the particles follow a path, use the Speed By Icon operator on page
2876 and use Path Constraint to assign its icon to the path. For a procedure, see
Example: To send particles along a path: on page 2877.
To employ deflectors for particle dynamics, with or without the Force operator,
use the Collision test on page 2960 and Collision Spawn test on page 2964.
