On a Livestream Chance once said he uses a Billboard for his root on all Blueprints and I’ve been doing the same ever since…works well…so Add a Billboard Component in your blueprint and drop it on the DefaultSceneRoot and it’ll replace it…then turn off Visible in the Rendering tab in the Details panel…
If memory serves you should be able to change the size of this billboard rendering as well without changing the size of the Blueprint actors below it so you can make it smaller rather than making it go away entirely…your call…
