Hi Mary Beth Burns,
Though I only recently started using multiple cameras in my projects, they do not all need to be all in one setting. For example, my first camera is to adjust settings for a simulation I am making and the second is moved out of the control panel and can be controlled by the user (with walk). To set up multiple cameras I used this code:
The main premise of this code is that on an activate of a button the camera is switched to the second. You start by giving your cameras names and enabling them in blockly. You then set then as variables and use the JS as I have.
I hope this help,
