 # UniPhys-Bench
 
-UniPhys-Bench is a human-verified benchmark for evaluating unified physical
-grounding on heterogeneous articulated 3D assets. It jointly evaluates
-articulation semantics, articulation structure, part-level intrinsic physical
-properties, and object-level scale and mass.
+UniPhys-Bench is a human-verified benchmark comprising 1,927 heterogeneous
+articulated 3D objects across two releases. It jointly evaluates articulation
+semantics, articulation structure, part-level intrinsic physical properties,
+and object-level scale and mass.
 
 This repository is the **primary UniPhys-Bench release**. It contains 1,473
-articulated assets provided by [Manycore Tech](https://www.manycoretech.com/)
+articulated 3D objects provided by [Manycore Tech](https://www.manycoretech.com/)
 (群核科技), with part decompositions created by professional designers.
+The remaining 454 evaluation-only articulated 3D objects are released separately
+as [UniPhys-Bench Part 2](https://huggingface.co/datasets/breezexian/UniPhys-Bench-Part2),
+completing the 1,927-object benchmark.

+Each row follows one articulated object from its original textured mesh through
+part decomposition and affordance grounding to the motion of all articulated
+parts. In the affordance view, **redder parts indicate higher interactivity**.
