"Adding Matinees
Now when we have main camera create two matinee actors. Still in persistent level:
MatineeActor_MoveToLevelSelection,
MatineeActor_Armory,
MoveToLevelSelection.
Click Open Matinee in Details Panel when MoveToLevelSelection matinee is selected. This will show up matinee editor. Matinees are really powerful and you should learn how to use them! I suggest spending some time watching youtube tutorials about Matinee and try to create something by yourself."
It include a link to matinees.
Learn from there then you will get there
