Activate Effect

Just make sure that one of the Warp Effect gameobjects is activated in the hierarchy.

Start the scene and simply press space to activate the effect. You can disable and enable the warp effects in the hierarchy without needing to stop your scene. All the enabled effects will start when pressing space.

You can also change the warp controller configuration during runtime to play around with the effect and find a configuration that suits you the best. (But please make sure that you copy the values before you stop the game, otherwise your changes will be gone!)
