Create goals

You can make nParticles 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 Goal Options).

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

1. 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.

2. Shift-select the object you want to become the goal.
3. Select nParticles > Goal.
4. To adjust the goal’s influence, see Edit goal attributes.
5. Play the animation to see the particles move towards the goal.
   Note: To make particles follow the object’s transform rather than its particles, CVs, vertices, or lattice points, you must select nParticles > 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:

1. Select the particle object or soft body you want to be affected by the goals.
2. In the workspace, shift-select one of the objects you want to become a goal.
3. Select nParticles > Goal.
4. Deselect all objects and repeat the previous steps for the next object you want to become a goal.
5. To adjust the goal’s influence, see Edit goal attributes.
6. Play the animation to see the particles move towards the goal.
