Hello guys,

Working with experimental class 3D widget I got some crash from the Editor (4.13.2).

Here is the step to reproduce the crash :

  • Open an new empty project
  • Create an User Interface > widget class, called “UMG”, you can let it empty
  • Create an new Actor BP called “3DWidget”
  • Add a component to this actor of class Widget (experimental section)
  • Set the Widget class to “UMG” in details Panel > User Interface
  • Check the checkbox : Draw at Desired Size

Once this checkbox is selected, the editor crashes if you have a visible opened viewport (Sometimes If you open the viewport of the my3dwidget or the actor is spawned during play / placed in level from viewport editor).

Here is the : stackTrace

In the attached zip file, there are the 2 uasset (actor and umg) placed at the root of Content/ folder

Hope this helps.
