"Time passes the same for the entire project"
I don't know what you mean.
Do you mean that all the event sheets run at the same time?
I think you must be mistaken, because only the event sheet linked to a scene can run at the same time, except in the way you mentioned, by including in the scene all the sheets I want in the one linked to this scene.
I'm right, aren't I?
Thank you for your help.
