When I teach my vILT Articulate Storyline 360 classes, we tackle scene creation right away. As the project grows and more scenes are added, students quickly realize that the scene numbers can get out of numeric order. For instance, scene 6 might end up becoming the starting scene and be listed first in Story View, scene 4 might be the next scene, followed by scenes 3, 5, 1, and 2.
In the example below, notice that the third scene is numbered 2, and the second scene is numbered 3.
I've never been bothered by scenes that are out of numeric order. However, I know that this bothers other Storyline developers. The Index tool allows you to quickly renumber your scenes.
Here's how it works. I've selected the last scene in the image below, titled Second Scene.
