`Flat-Object-Assets/` contains 21 semantic category folders and 104 packaged assets. Each asset package contains its SimReady metadata, its entry-point USD under `simready_usd/`, and all associated dependencies. Preserve the directory hierarchy when downloading or relocating the assets because USD references may be relative.

`Flat-Object-Assets.zip` provides the same asset collection as a single downloadable archive.

## Download

```bash
hf download Hwsss/FlatLab-Asset \
  --repo-type dataset \
  --local-dir FlatLab-Asset
```

## Usage

Open an entry-point file such as `Flat-Object-Assets/Book/Book1/simready_usd/Book1.usd` in a compatible USD application or reference it from an NVIDIA Isaac Sim scene. On the Hugging Face Hub, click an entry-point `.usd` file to open the OpenUSD Viewer. Some objects use PhysX collision/contact simulation and some deformable objects require Position-Based Dynamics support.
