Thanks guys, all that advice really helped. I think I have a good idea now how I can get all of this to work.
One thing I'm wondering is: Is there a way to just temporarily switch to another layout to tell the story further? Say, I'm on layout 2 and a certain event happens - Now I want to put in a cutscene and only temporarily switch to layout 11.
Layout 11 has a 'Start of Layout - Play Timeline' event assigned to it, so it'd automatically start playing as I temporarily switch to it. And when the timeline is over, I'd want to switch back to the exact same position I've been before - isn't that somehow possible?
Switching temporarily to another scene is vital in terms of cinematography to give the player more background in terms of story or tell him something about a character - This would be my Nr. 1 feature request if there's not any workaround in there to achieve this.
Most of the other framework is already done - creating detailed cutscenes is one of the last big things I still have to tackle.
Deadeye: I loved the TCR Intro / Cutscenes. I know it's a bit much to ask, but would you share the cap with us? Even if the timeline object would make things a little easier now, I'd love to see how you tackled the problem and how convoluted it got.
