Using a 3D Object

You can use a 3D object as a particle generator. Particles are generated from the centre of each polygon.

To add a particle stream using a 3D object:

1. Select or add the 3D object that you want to use as a particle generator.
2. With the 3D object node selected in the schematic, do one of the following:
   - Drag the particle generator node from the node bin and place it in the schematic.
   - Double-click the particle generator node. You do not need to be in Schematic view to add a node in this manner.

   A particle generator object is added and automatically connected to the selected 3D object.

3. Set the particle generator's properties. See Customizing the Particle Stream.
4. If you do not want the 3D object to appear in the scene, hide the model in Schematic view. A particle stream is generated from the hidden model.
