NOTE When Lock On Target Object is off, more calculation is required because
the system might have to recalculate each particle's optimal target point in each
frame.
Docking Direction group
Docking type Lets you specify from which direction particles should approach
targets.
■ None Specified No docking constraints. Particles reach their targets in
the most efficient way, based on their assigned parameters and their current
attributes.
■ Along Icon Arrow The final direction is the same as the Find Target icon
arrow.
NOTE When using this option, arrows appear on the Find Target icon to
indicate the direction particles will use for docking. You can change the docking
direction by reorienting the icon. This applies even when using mesh objects
as targets.
■ Icon Spherical The final direction points toward the center of the operator
icon.
NOTE When using this option, arrows appear on the Find Target icon to
indicate the directions particles will use for docking. You can change the
docking directions by reorienting the icon. This applies even when using mesh
objects as targets.
■ Icon Cylindrical The final direction points toward the icon arrow as a
line, thus forming a cylindrical field with the arrow as the cylinder's main
axis.
NOTE When using this option, arrows appear on the Find Target icon to
indicate the directions particles will use for docking. You can change the
docking directions by reorienting the icon. This applies even when using mesh
objects as targets.
■ Surface Normals Each particle reaches its target point from a direction
perpendicular to the surface at that point.
