I want these builds, player built walls, not props which are in one area to spawn in a different area. How do I do that?

Level instances aren’t in UEFN. Player built walls aren’t consider creative props. What do I do?

You can’t clone live player-built walls to another spot. Level Instances are not in UEFN, and Fortnite grid pieces are not creative_props, so there is no “copy this wall actor over there” call.

What actually works:

  1. Don’t use player builds as the source of truth. Treat the structure as data: piece type, grid cell, rotation, material. Rebuild it at the destination with Building Props or your own meshes. That is what the Procedural Building template does (voxels in → meshes out, wherever you want).
  2. If players must build with the Fortnite piece: listen to place/destroy as well as you can, write the grid into a map, and spawn props at an offset. You will not get a 1:1 Fortnite wall with edit-select and the same health; you get a replica.
  3. Editor-only copy (you building in UEFN, not players at runtime): select the pieces, duplicate, move. That is it. No device for “this playspace rectangle, again, 50m over”.

Prop-O-Matic / capture devices only see props. Player walls will not show up there.

If the goal is “build here, play the same layout over there”, design the build as props or a voxel grammar from day one. Fighting the Fortnite build grid into a second location is a dead end in current UEFN.
