+# Objaverse-XL Rigged & Animated — Renders
+
+Visual companion to
+[**Linzhan/Objaverse-XL-Rigged-Animated**](https://huggingface.co/datasets/Linzhan/Objaverse-XL-Rigged-Animated),
+which holds the 7,373 rigged-and-animated GLB assets themselves. This repository holds only what
+was rendered from them: a four-view video of every animation clip, and a rest-pose grid per asset.
+
+They live apart from the assets because they are bulky and numerous — 10,355 clip folders — while
+the asset repo stays a compact 7,373 GLBs plus two tables. Nothing here is needed to use the
+assets; it is for previewing motion on the Hub, for VLM captioning, and for eyeballing a rig
+before you commit to processing it.
+
+| | |
+|---|---|
+| clip renders | 10,355 folders · 41,420 MP4s (2.2 GB) |
+| rest-pose grids | 7,373 PNGs |
+| rendered frames | 957,818 per view (~8.9 h) · 3,831,272 across four views |
+| resolution / rate | 512×512 · 30 fps |
+
+## Contents
+
+```
+glb_render/       10,355 dirs   four-view render of every skeleton-driving clip
+tpose/             7,373 .png   rest-pose render grid per asset
+```
+
+Stems match the asset repo exactly, so both join back to `metadata.csv` / `animations.csv` there
+without any name mangling.
+
+## Renders (`glb_render/`)
+
+A four-view render of every clip that drives a skeleton and runs at least 5 frames — 10,355 of
+the 16,190 rows in the asset repo's `animations.csv` (the rest animate only non-joint nodes, or
+are too short). One folder per clip, named `{glb stem}-{action}`:
+
+```
+glb_render/00064e6f6eec4fd7acf27091b8de4d70-Object_4/
+  v000.mp4  v000.json      front  (azimuth  -90°)
+  v001.mp4  v001.json      back   (azimuth  +90°)
+  v002.mp4  v002.json      left   (azimuth  180°)
+  v003.mp4  v003.json      right  (azimuth    0°)
+```
+
+An asset with several actions contributes one folder per action; distinct actions that sanitize
+to the same name get a `_00`/`_01` suffix in discovery order, so folder names stay unique.
+
+Rendered with Blender EEVEE at 512×512, 30 fps, elevation 0, and composed into one H.264 MP4
+per view — the transparent-film frames flattened onto a light-grey background, since H.264
+carries no alpha. The MP4s preview each motion directly on the Hub; the per-frame RGBA PNGs
+behind them are not hosted (they would add roughly 2.9M files), so extract stills from the MP4s
+(`ffmpeg -i v000.mp4 frames/%04d.png`) if you need them.
+
+Rendering covers the first 200 frames of a clip (~6.7 s); 2,150 of the 10,355 clips are longer
+and are truncated — `frame_start`/`frame_end` in the per-view JSON record the covered range,
+not the source range.
+
+Each `v00X.json` holds the camera in NeRF convention: `view`, `azimuth`/`elevation` (radians),
+`resolution`, `camera_angle_x` (horizontal FoV, radians), the 4×4 camera-to-world
+`transform_matrix`, the `scene_scale`/`scene_offset` that normalised the asset into frame,
+and `frame_start`/`frame_end`/`fps`.
+
+## Rest poses (`tpose/`)
+
+`tpose/<stem>.png` is a 1024×1024 2×2 grid of the asset's rest pose — front and back on the top
+row, left and right below — rendered (EEVEE) from its GLB, one per asset in the asset repo's
+`glb/`. Useful for classifying an asset's body plan without importing it.
+
+These previously lived in the asset repo and were moved here so that everything rendered sits in
+one place.
+
+## Usage
+
+```python
+from huggingface_hub import snapshot_download
+
+# just the rest-pose grids
+snapshot_download("Linzhan/Objaverse-XL-Rigged-Animated-Renders", repo_type="dataset",
+                  allow_patterns="tpose/*")
+
+# one clip's four views
+snapshot_download("Linzhan/Objaverse-XL-Rigged-Animated-Renders", repo_type="dataset",
+                  allow_patterns="glb_render/00064e6f6eec4fd7acf27091b8de4d70-Object_4/*")
+```
+
+## Licensing and attribution
+
+These renders **depict third-party assets** and are included as visual reference. They are not
+covered by any blanket licence: each render inherits the upstream licence of the asset it shows,
+exactly as that asset's GLB does. Resolve the licence for a given `object_id` through the
+Objaverse-XL annotations before using or redistributing a render, and see
+[`NOTICE.md`](https://huggingface.co/datasets/Linzhan/Objaverse-XL-Rigged-Animated/blob/main/NOTICE.md)
+in the asset repo for the full statement and the takedown process.
+
+Rights holders who want an asset removed can open an issue on either repository.
