Sorry my delay guys. I had a couple of busy days in a row.
Ashley - It works, and I made some tests to have a auto-scroll on rail camera based on triggers. The zoom is the only issue right now. I know how to scale the layout, but how can I make a transition between the zoom levels using just the engine without plugin?
linkman2004 - Your plugin is great and it fits in almost everything that I need. I still have some doubts about some issues and I sent you a private message about it. Thanks!
sosensible - I used the behavior. To resolve the layout edge problem I made a invisible collision on a fixed layer that doesn't allow the players to leave the layout when they are too far from each other. Isn't the best solution, especially because you have to use it on the max Zoom Out to work well.
