I had the problem where it was not animating and managed to fix it.
The problem is in the blueprints the “Cast to VaOceanStateActorSimple” node was failing for ALL actors, including the VaOceanStateActorSimple I had in my scene.
I deleted the node and re-created the same setup. I also changed the “Get All Actors Of Class” and specified VaOceanStateActorSimple as the Actor class to filter.
