Hello,
just wanted to ask if I can lets say create a level that is just house. And then just copy that house to another level.Thanks.
I think it would be better to convert that to a prefab(Blueprint) and then place that into the level(s).
There should be a “convert to blueprint” option somewhere when you right click on the selected actors.

You can just select whatever you want to copy, copy and paste using ctrl+C and ctrl+V.
