PMD model head is not in place!

[NadeshikoLove]

in my first MMD I need a Len model with cantarella clothes, I cant find any model... soo I decided to make one, I put a Len head and the clothes that I need and I save it, but when I open MMD and move len, just the clothes move and the head remains in place, floating!
what I can do to fix it?!There is a way to "merge" it?! e_ej

Okay, so the problem is with the bones, not the actual model. What you need to do is make sure the "head" bone's mother bone is the "neck" bone. The "neck" bone's mother bone would be the "upper body" bone. Make sure these three bones are connected and it may work. If it still doesn't work, check the weight. Make sure that Len's head is weighted onto the "head" bone. If not, fix that issue.

Hope this helps!
