I've created an action to add a duplicate hotspot with different values to get over the problem I found in this post . i.e. you need 2 hotspots if you want to have a graphic in a polygonal hotspot.
Ideally this would be called when each hotspot is loaded, but onloaded="" doesn't work on a hotspot.
Is there a way of creating an action that can be run when the scene is loaded that applies my action to all hotspots?
