Thanks for the response, and the explanation on how the templates work! I had no idea they read from the source level, and instead figured it was a sort of "snapshot" of a level's configuration.
I've got a basic understanding of how it works. I was actually re-saving the entire template over the original every time I made a change, which took quite a while.
Now I'm just trying to position the cameras/icons in a way that produces an aesthetically pleasing portrait, because for some reason the mirror ALWAYS defaults to the blue portrait in the human male location and I'm currently not sure how to change that.
Thank you, again!
