I am trying to make the Bone 1 copy 50% rotation of Bone 2, as below. Mixed axis of the bones make it difficult. Please, what should I do? I spent hours trying, I will do everything you say.
I created a fresh armature in simplest way, and found that Local Y axis in bone 1 is Local axis Z in bone 2. Why does this happen? I would expect the bones to have the same local axis alignment?
Is there a way to make Local Y rotation of Bone 1 copy the Local Z rotation of Bone 2 with 50% influence?
