Sorry. Just because rigging is difficult or is there something specific to the model making it difficult?

I 'll try to explain what happen. this model has closed eyes. so ... it turns more difficult to parent metarig to the model, in order to move the eyelids., also ... the head has various "shapes" and other elements, all in just one mesh, making rigging hard to achive.

I see. If you go into edit mode and select all, you can press P to bring up the separate menu and choose "by loose parts." That will separate out all the mesh pieces for you, which should make it easier if you need to isolate certain parts (hair, candies, eyes, brows, etc). The body and head are all one piece, but you can use the same method by selecting what you want and choosing "by selection" from the separate menu (P).

wish you rigged it but otherwise its awesome

Thanks!

Thank you!
