I mean place in a Blueprint a BSP is not possible, place in a Blueprint a collision volume or pp is not possible, and place in a Blueprint other blueprints, not components is not possible, if you have there a logic as the post made by Dead Island 2 guys is not possible to make a complete house with sub blueprints that have door logics, physics logics, and light logics. And NO THE Blueprint COMPONENTS DON’T REPLICATE PHYSICS. Out of that if you do for each house all from ground to make each house logics cause you need components then is better don’t use Prefabs in that way at all and use the normal BP and replicate it in that way…
