Having the same issue:
- Create a UsetWidgetBlueprint (A)
- Add a button to (A)
- Call Button.SetStyle on (A).EventPreConstruct and set to a ButtonStyle variable.
- Inherit (A) as the parent of a new UserWidgetBlueprint (B)
- Change ButtonStyle on (B)
- Compile
- Add (B) to ActorBlueprint as WidgetComponent
Expected result: the WidgetComponent displays (B) with the set ButtonStyle variables
