Creating a Sub-System

Sub-systems provide a solution for multiple use cases: you can create a custom hierarchy with sub-systems, or create different behavior when entering each sub-system.

To create a sub-system:

1. right click in scene hierarchy, and choose LLS > Create > Sub System.
   This will create a new object in the scene under the Devices object.
   This object is a container for one sub-system.
2. Select your objects to isolate and drag them into the Device Elements field.
   In the Device Elements section you can add custom elements for the sub-system. these elements can be isolated when using the 'isolate' option in the sub-system.
3. Select the Sub-system camera location object to set the view for the current sub-system.
4. Select Control Shift F to snap it to your current view location.
   Now the subsystem is set up with relevant isolation objects and location.
5. In play mode, click on the sub systems button, and in the sub-system click on the isolate button.
   The objects that we added in the Device Elements field are now isolated.
6. To center the pivot around the model: In our scene, select the sub-system camera location object, and drag it to the center of the model.
7. Now in the Sub-System object itself, open the Main Location attribute, and change the Z Distance to 1. This will set a distance for the camera by 1 meter. but the pivot point will stay at the model, so we can rotate around it.
