yes i noticed too that plugin does not always work in MZ either , i'm not sure why. can't really complain with free plugin but still..i would not want to buy a plugin and not being able to use it that for sure.
yes when creating a character all the animations come along it's really good , and can change the face between smiling ,crying ,being angry and such :)
that's a lot of pictures and sprites to convert if you choose to use MV :(
