there are two comaptibility ^^;
(I know,, it often confused user)
1 is compatibility base, it need only o set about figure.cr2 or accessory or, prop,hair
you can load the object by click these icons.
then when you declared as ,, means,, you set compatibility base..
2 is comaptibility with.
you set materials and morphs ,,, compatibility base as Generation 4> Victoria 4.
simply think,,, material is not Victoria 4, as you know.
so you need to remove compatibility base,, from morphs and materials or poze files.
these files can not have compatibility base, need not set compatibliity base.
on the other hand,,
you need to set compatibility with
that means,, each material presets or inj or rem files are need comaptibility with, figure or prop etc,
when you select the those base , if presets are assgiend with the base (by compatibility with)
you can show them on smart content.
and I recommend,, almost every V4 material preset are work not only V4 but Also genesis,
so I set compatibility with,, (V4 and genesis) you can set two or three compatibility with..
it seems important,, .
