[Solved] Empty Viewport

Hey folks,

I’ve got a small problem with one of the blueprints I’ve created; the viewport in the editor is completely empty:

The blueprint is derived from a C++ Actor class, which has a UStaticMueshComponent (in this case a +), a UShapeComponent for collision (UBoxComponent) and a USceneComponent as the RootComponent.

The strange thing is that the blueprint works perfectly in-game; all of the events are firing and it’s visible:

I’ve tried restarting the editor, hitting ‘f’ to focus on a particular component, resetting the viewport… but nothing seems to work.

Any ideas what I could be doing wrong here?
