Hi,  
the “global structure” of the .baylon file format has a top level “actions” property.

How do I add an Action to a Scene so that it is exported to the top level “actions” array. (I’m not refering to actions of e.g. a mesh )

The global “actions” property in a .babylon file comes from the serialization of `scene.actionManager` (if defined).

So, you must set a value to `scene.actionManager` and register actions with it to populate the global “actions” property.

Just for fun, I asked ChatGPT:

The answer is the right one, except it is missing `scene.actionManager = new BABYLON.ActionManager(scene);` in the code example!
