Unreal Engine any scene component causes sliders to lag?

Does anyone else have this issue? Is it an engine bug, or do I have some settings wrong? I really need to figure out how to make this smooth as I have a blueprint that involves lighting and I adjust the lighting on the blueprint instances, but it’s currently so laggy that it’s almost unusable, and the only way I can reduce lag is to remove every single component.

  • Create a new Blueprint
  • Add an instance editable variable that can be slid, like a float or int
  • Bring the actor into the world and slide the slider. It slides smoothly so far
  • Now add a scene component to that blueprint. An empty scene component, static mesh, etc.
  • Now try sliding the slider of the variable. Suddenly it’s real choppy and laggy and stutters, especially if you drag it quickly!
