Evidence stage
CapabilityA demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.
Tasks this bears on

Where this applies
A research method for automatic rigging and skinning of 3D models. The authors report that it significantly outperforms state-of-the-art academic and commercial methods, achieving a 215% improvement in rigging accuracy and a 194% improvement in motion accuracy on challenging datasets, and note it might struggle with highly unusual skeletal structures such as those in abstract or highly stylised characters. The benchmark uses the authors' own dataset; one author is from a company that sells AI 3D generation tools.
What this means
Rigging — hours of expert work per model — is being automated in research, but stylised characters, the kind animation relies on, remain hard.
What it does not yet show
A benchmark on the authors' own dataset; it does not show studio use.
What you can check
Open the UniRig paper on arXiv (2504.12451) and find "215% improvement in rigging accuracy".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
