By Downgrade, I had meant a second install x- x and even then wouldnt work with Newer Blueprints - 3-
SMedit is mainly only used for making Shells currently.
Of Course you could make your Ship's shell in the pre 0.14 Version, and then load it in and edit it, then Load the edited Version into your latest version and let it convert :/
I dunno, SMedit requires a little bit of thinking if you want to use it anymore - 3-
