Animate goal behavior
The techniques for animating goal behavior follow:
- You can animate a goal’s influence off and on with a key, expression, or other animation
technique.
- You can set keys to animate the value of the per object goal weight.
- You can tune the effect of goal weight animation as the goal weight increases or decreases
over time.
To key a goal’s influence off (or on)
- Select the trailing particle object.
- Display the and open the section.
If the trailing particle object has multiple goal objects, there is one entry for each. Each is listed under the goal weight slider named after the goal
object.
- Turn off.
- Key the attribute (see Animation).
To animate the value of per object goal weight
- Set the value of the goal weight as described in Set goal weights on a per-object basis.
- Key the attribute.
You cannot set keys for per particle goal weights.
To tune goal weight animation
- Select the trailing particle object.
- Display the and open the section.
- Set the to a value of 1 or greater, as follows:
With a of 1, the goal weight effect increases proportionally as goal weight rises in small
increments from 0 to 1. For higher values of , the goal weight effect increases slowly as values rise above 0, and quickly as the
values approach 1. Objects have a default of 3.
