Im pretty intregued by this as this type of tool could do wonders for those in the Mario Kart Moding scene. Hopefully this might become a stand alone tool?

I considered it, but I rely on the Godot editor viewport and I'd need to make a custom fork of Godot itself, which is actually something I might try in the future, in order to make a standalone Vertex Studio version experiment (so there would still be the Godot plug-in and a standalone version side by side) .
