Quick facts:
The Machinima Maker is part of the vhAssets package. It is loaded from inside of unity by clicking the "VH" menu on the menu toolbar and then clicking "Machinima Maker"
If you have no previous cutscenes in the unity scene, then when you load the Machinima Maker window, there will be 1 single button that says "Add Cutscene." If you have previous cutscenes in the scene, you can add a new cutscene by clicking the + button next to the word "cutscene"
Click the - or + sign next to the "Track" text at the top center of the window
There are several ways to create new events for a cutscene
Upon selecting an event with left click, you have access to the "Event" tab on the user interface. Here you can set event properties such as event name, start time, and event type. The event type is a category (such as Audio or SmartBody) that provides access to functionality that is inherent to the type (like playing a sound or using locomotion). Event types provide easy access to this functionality.
Once the event type is selected, choose the functionality that you want the event to perform when invoked. Once chosen, make sure you will out the required parameters listed below the selected type.
