Well it seems like this feature will have to wait, I will have to implement the multiplayer building support first ( which I already know how to do without start digging in how to make plugins and stuff ).
The idea of this level editor is that I won’t have to release the whole project files and still let the user make his own stuff. It will have to get much better in order to use it with the unreal editor itself.
I still need to figure out how to make something that is actually useful with the proceduralmeshcomponent ( so it can make stuff like ProBuilder for unity does ).
