Ok, great!
Yes, the camera not rotating was the detail we needed. Because there are a few things here- it could be not switching to that camera, it could be showing a black screen, and so on.
Try going off of the “Cast Failed” options on your casts and using a print string there- if it isn’t casting it’s not giving the return object.
If it is not failing, try right clicking the “As Binded Character Top Down” and promoting it to variable, then use that variable as the input for the “Get Actor Location” for the lookat node.
