Bondage Hamster

not always but when it occurs which bone is never be fixed.

I don't know how those Parent Bone could affect to their own Child Bones while Bone Compensation Activated.

so I've Record this Weird Parent Bone for guys who would help me.

as you can see, I've check the Bone Compensation before key the Parent Bone.

then I've keyed some Translate of Parent and Press the 'K'. but you see that Children Bones?

I'm Really Sicked with this Problem for a Long Time so Please Someone Help me.

I've upload a Project on this Thread.

When you use bone compensation, it's actually changing the children. So you also need to key the children that moved.

You need to press K (key all) to be sure all changes are keyed— including children or unrelated bones.

Also, remember that transform channels/items/timelines won't animate before the first key (which I think is part of what's happening in the video). You didn't actually key the transform on the child bones on "frame 0"
