You can connect a particle object to an emitter that is currently connected to another object.
For example, you can create a curve with two directional point emitters, emitter1 and emitter2. Emitter1 emits particle spheres to the right, while emitter2 emits particle streaks to the left. In the following figure, the spherical particles are particle1 and the streaking particles are particle2.
If you select particle1, the Dynamic Relationships Editor shows that it is connected to emitter1.
You can select either, neither, or both emitters in the right panel to connect them to particle1. If you connect particle1 to both emitter2 and emitter1, Maya emits spheres from both emitters.
