Using standard morphs helps since we don't have to worry about how to make the custom morphs into loadable assets. A character preset will store morph and material settings, ready to be applied to a newly loaded base figure - packaging that would be a matter of setting up the RuntimeTextures folder as DM describes, though a Character Preset is a native file so should be saved outside of the Runtime folder. If you want to store a character with hair, or with clothes, for your own use the simplest solution is to save a Scene Subset. The other option is to use a Wearables Preset for the hair or clothes and a character preset for the actual character.
