Streaming Terrain (generate Tiled Landscape)

I have already made the terrain, vegetation, and actors and then placed all of these together. The problem is we now need to split all of this into a grid system for level streaming. Is there an easy way to select an area and split it off into its own level? Or am I sol.

example of: World Streamer Tutorial 3, 4 - Terrrain split and terrain culling system. - YouTube

You should use World Composition to split the world into tiles.

thank you very much

Answer worked. For those using Wwise remove or disable the plugin for this task.

unreal change vegetation assigned level

I can slice the terrain into tiles and assign them to each of their own levels however the vegetation will not follow the tiles. Is there a way to transfer placed vegetation to selected level.
