A work around that works…
- Create an actor blueprint derived from the StaticMeshActor
- Set the mobility for the static mesh component to moveable
- Add this to your blueprint in the event graph
Create a static mesh plane in whatever application that suits you but make sure that the plane is facing positive X and that the UV map is placed the same so it also face positive X. Set the plane as static mesh in your newly created billboard actor and voila.
