Masterpiece X output is a starting point, not proof that an asset is production-ready. A rig readiness pass should distinguish generation artifacts from deliberate form before anyone spends time polishing the result.
For Masterpiece X output, use a short representative clip to verify joint names, rest pose, frame range, root motion, and deformation. Preserve the source rig until rigid-part separation passes review.
Check edge flow around joints, neutral pose, separate rigid parts, naming, and expected deformation before rigging begins. Apply this rig readiness guidance to the actual Masterpiece X output delivery path.
