+# Squishy 3DGS Assets (Test)
+
+> **Note:** These are test assets for development and evaluation of the squishy physics simulation pipeline.
+
+Pre-trained 3D Gaussian Splatting (3DGS) scenes used by the **squishy** physics simulation project. Each `.zip` contains a full `gaussian-splatting`-format output directory (PLY point cloud at multiple iterations, cameras, images).
+
+## Asset Origins
+
+**All 3DGS scene assets in this repository are open-source assets from [PhysGaussian](https://github.com/XPandora/PhysGaussian)** (Xie et al., CVPR 2024), mirrored here to the Hugging Face Hub for convenient access. We did not train these — full credit goes to the PhysGaussian authors.
