Yeah I thought there would be problems after looking more deeply into it, that it is only for pre-made levels. The problem is I want the world to be “editable” (you destroy this tree, its gone forever, you build something, its there forever) and for that I need at least some data structure/saving. I want to save the least possible and get the most out of seeds such as floor like in Dont Starve that serve as basis for the world could be one such thing that really does not save, but objects like buildings etc. I would need to save and load. Any ideas? I am newbie to unreal so everything helps.
