Its not a problem, the VARS dont have a SCENE nor a PRESET. I dont know if im losing myself on the translation but you wont be able to load SCENES/PRESETS from those VARS, if you open them and they dont have the "Saves" directory and in the meta.json you only see morphs and textures its because thats the way the author wanted it, its not an error, you just have to work to get the complete look. Im sorry but i already explain this in detail, this has nothing to do with your VAM installation or any other thing, just do this:
Start an EMPTY scene
Add a default person
Go to female morphs and search for MaF morphs: Hana Head (MaF), Base Body (MaF), Sexy Body (MaF), Dosukebe Body (MaF)
Play with them until you get the results you want, normally one head one body to 1 (100% of slider)
Apply skin textures "MaF.MaF's_OC_Hana.3.var\Custom\Atom\Person\Textures\MaF\Hana" for example
then go to hair, disable the default one (unselect it) and add the one that comes in the var (Bob1), you will get the entire look.
I wont be able to help you more if you cant translate it or understand it at this simple level, but i truly wish you do so you can enjoy the look.
