already have problem after RX21 update (Patreon)

I already updated Onikata Kayoko 2 posts with fixed card.... or you can fix it manually, I show it on screenshots (material editor in eyes tab)

half of my characters have been affected by this problem.
ok I fixed 19 characters that have this problem and already updated their posts.

all characters are now checked for compatibility with RX21 and RX20, in both versions everything now works fine.... I hope there are no other bugs =_=

EDIT: added a screenshot of characters that have problems with eyes and hair after RX21 update

if you have my character from very old posts, but have already downgrade your membership to 4$, then write me a message and I can give you a fixed version for RX21 game (if you show me the original), or you can fix it manually as shown on the screenshots

I hope you treat this with understanding ＜(。_。)＞
