-This is the **raw, unprocessed** Objaverse-XL source pool behind the `UniML3D` dataset used by
-**UniMate** (SIGGRAPH Asia 2026), which generates articulated motion for arbitrary skeletal
-topologies from a text prompt. UniML3D combines this pool with Truebones and Mixamo, then applies
-filtering, semantic annotation and canonicalization; none of that has been applied here, so the
-pipeline can be reproduced or replaced.
+Objaverse-XL indexes over 10 million objects, but only a small fraction carry a usable rig **and**
+motion on it. This subset isolates that fraction: every file was checked to contain at least one
+skin with joints and at least one animation clip that actually drives them.
+
+Assets are provided **exactly as downloaded** — no filtering, retargeting, canonicalization or
+joint renaming has been applied — so you can run your own preprocessing on top. The accompanying
+tables expose the structural properties needed to plan that preprocessing, such as which assets
+have a disconnected skeleton or which clips are near-static.
