Hi everyone! 
Has anyone ever implemented a building system like in The Sims 3 / 4 (or RTS) in Unreal Engine 4 / 5? For a life simulation game or RTS.
I need some tips how I can realize such a building system. Starting from the landscape changes (the player should be able to raise and lower the terrain, e.g. to place pools or cellars). I have no idea, how to realize this.
My first thoughts on this are:
- The landscape in UE 5 is not editable at runtime → so my idea is to leave holes in the terrain and place plots of lands there, which are generated prozedural and the player can change them. Is this a good idea? Are there better ones?
- How can I draw a Grid like in this video?

Do I need to place actors there? Or are there some commands to draw lines in the world? - How can I generate walls and replace the materials / wall painting / wallpaper at runtime?
- How can I hide the ceiling or walls, if the player is inside of the house?
Thanks for your advice!
