You
can make a particle or nParticle object move towards one or more
goal objects with the following procedures. Note that you can create
a soft body with its original geometry as its goal (see
Create soft bodies).
NoteThe following sections
are also applicable to goals that are created with nParticles.
If you make a trimmed NURBS surface a goal
object, all its CVs become the goal, including the CVs where the
trimmed area exists. To correct this, convert the NURBS surface
to polygons with
Modify > Convert > NURBS to Polygons and
then add the goal.
To connect a particle object to a single
goal object
- Select the particle object you want to
be affected by the goal.
To select a soft body
rather than a conventional particle object, you can select the soft
body’s original geometry or its child particle object.
- Shift-select the object you want to become
the goal.
- Select
Particles > Goal.
- To adjust the goal’s influence, see
Edit goal attributes.
- Play the animation to see the particles
move towards the goal.
NoteTo make particles
follow the object’s transform rather than its particles, CVs, vertices,
or lattice points, you must select
Particles > Goal >
to display
the
Goal options window. Turn on
Use
Transform as Goal in the
Goal Options window
before you add the goal.
To connect a particle object to multiple
goal objects:
- Select the particle object or soft body
you want to be affected by the goals.
- In the workspace, shift-select one of
the objects you want to become a goal.
- Select
Particles > Goal.
- Deselect all objects and repeat the previous
steps for the next object you want to become a goal.
- To adjust the goal’s influence, see
Edit goal attributes.
- Play the animation to see the particles
move towards the goal.
