Hi Malcolm,
While it's not impossible, using Scripting to change the names of the SceneDirector would seem a bit silly to me.
I would actually use Visual Logic for this.
Create 20 Scene Directors to take out the respective Case and in each of those Scene Directors, use a Scene Director Trigger to trigger the Out SceneDirector.
Now this will cause some conflicts because I assume you will have an out animation of the case you have selected also in the OUT Scene Director which will conflict with the individual case off-animation.
So you would need to take that into consideration.
