Creating a Trigger
Use the 
button to add a trigger. Two types of triggers are available:
Type | Function |
|---|---|
Mouse | This type of trigger plays a clip or a timeline when you click on a specific surface in the scene. |
Keyboard | This type of trigger plays a clip or a timeline when you press a specific key on the keyboard. |
First, select the type of trigger.
For a mouse trigger, select the surface, or kinematics node. You can do so using the list or by clicking on the 
button to use an eyedropper to pick a surface, a null, a vector or a rotation axis. When using a null, a vector, or a rotation axis, all of its child surfaces will function as triggers.
For a keyboard trigger, click on the button to record the keystroke that will function as a trigger.
