Missing arrows

drag, rotate, zoom arrows are missing, and the entire world is black at the bottom

Hi @AngFallen ,
You can try the following steps:

  1. Press G in case you accidentally enabled Game View, which hides all editor widgets
  2. From the top menu, open Window - Viewports and make sure you have the viewport tab open
  3. Inside the viewport, enable Show Transform Widget is enabled
  4. In that same window, you can use Load Default Editor Layout to restore Unreal’s default layout


And regarding this issue, could you also provide a bit more detail , which version of the engine you’re on, how it happened, and maybe a screenshot or short description of your setup.
Hope it helps!
