Hello, I have just started learning the software and would really appreciate some help. I have separately attached each head element to the head bone, but the head deforms when rotated. However, the body created in the same way works fine. Could you please explain my mistake. Thanks.

Hi and welcome to Spine! 😎

Just a programmer's guess: It looks as if you're using non-uniform scale (scale X not equal to scale Y) at the head's parent bone (the bone_girl_neck bone) or any of its parents, but have Inherit Scale enabled at the bone_girl_head bone. This will rotate the head in a "distorted" environment. To resolve this, just disable Inherit Scale at the head bone.

    Yep, it is as Harald said. However, I would suggest not disabling inherit scale if possible to solve it another way. If you do disable inherit scale, you won't be able to use scale to squash the whole character (though skeleton scale at runtime still can). Another way to solve it would be to make the torso or neck (whichever you are scaling) not need non-uniform scale, for example by changing the images.

      Harald Oh thank you so much! You are absolutely right, the (bone_girl_neck) has different X and Y parameters, but after disabling Inherit Scale for the (bone_girl_head) it messes up the layer 😅 Well, probably it's better to make a new neck and head bone.
