Can i run these scenes in an other quest if this quest is not running?
yes, you can run them from another quest,
no, you can't run them when their quest ist not running, as starting a scene also starts it's carrier quest
what exactly do you mean "pass scenes"?
if you mean start it from another quest, give that quest a script with a
scene property yourScene auto
fill that with your scene and then just go
yourScene.Start ()
(this will also automatically start it's carrier quest, as said)
or if you mean move a scene to another quest, in ck, you can just duplicate the quest and in one instance delete the scene out, and in the other one, well, everything else
or scenes can be quite easily reassigned to other quests with tes5edit (prepare a target carrier quest with fitting aliases in ck first though)
