heiser Hi!
Just so you know, the camera mode has nothing to do with the procedural generation, when you draw these lines, the walls are already drawn as well.
Look at the function called "BuildRoom()" I think this is what you want:
GameObject inst = Instantiate(proceduralRoomPrefab, roomsContainer);
ProceduralRoom proc = inst.GetComponent<ProceduralRoom>();
...
proc.Generate(worldPosList);
worldPosList is a list of vector3. There are taken from the points you put on the scene, and the component are then drawing the walls etc.
