Is there a way to convert an already existing Blueprint class working mostly on nodes into a plugin? If so, which one do I pick? The blueprint class consists of mesh and motion controller components.
Your title and question are conflicting a bit, do asking how to pack blueprint in to plugin or to convert nodes of existing blueprints? or something else?
May want to checkout the \Content\ folder for Plugins. This allows you to have .uasset files within Plugins which you can then share.
