A set of classes and methods that allow a Blueprint user to build Viewport tools using the underlying ViewportWorldInteraction module.

/ViewportScriptingUtilities/Editor/EUW_ViewportInteraction contains an example editor utility widget that sets up the viewport interactors.

Included examples of cursor interactor implementations:

• /ViewportScriptingUtilities/Editor/GreasePencil: Draws a bunch of debug points to simulate a temporary grease pencil.
  
• /ViewportScriptingUtilities/Editor/SplineDraw: If an actor with a spline is selected, will allow the user to hold the CTRL key and click to place spline points on the surface under the mouse cursor.
