-## What is in it
-
-- `glb/<asset>.glb`: one file per SimReady asset folder, named like the folder in the source dataset.
-- `manifest.jsonl`: one line per asset. It records size, triangles, draw calls and textures before and after
-  optimization.

-## How the files were made
+## What is in it
 
-1. Download `simready_usd/` from each asset folder. `source_assets/` is skipped because it holds a second copy of
-   the textures for MDL shaders.
-2. Check that `.metadata/LICENSE.txt` is CC BY 4.0.
-3. Import the USD in Blender 5.2 and remove the collision, proxy and grasp helper prims. Export a glb with the
-   original textures.
-4. Optimize with glTF Transform 4.5. Remove duplicate mesh instances, then dedup, prune and weld.
-5. Resize textures to 1024 px as WebP. Compress geometry with meshopt (`EXT_meshopt_compression`).
+- `glb/<asset>.glb`: one file per SimReady asset folder, named like the folder in the source dataset.
+- `thumbs/<asset>.webp`: a 512 px render of each glb, with `thumbs/metadata.jsonl` holding its category, size,
+  triangles and draw calls. The Dataset Viewer above shows this table.
+- `manifest.jsonl`: one line per asset with size, triangles, draw calls and textures before and after optimization.
 
-Five assets (two coilovers and three robot trolleys) use UDIM textures. For those, each tile is split into its own
-material before the export, with its UVs moved into 0-1.
+## Download
+
+All files, about 3.9 GB:
+
+```bash
+hf download codepawl/simready-glb --repo-type dataset --local-dir simready-glb
+```
+
+One category, for example every food model:
+
+```bash
+hf download codepawl/simready-glb --repo-type dataset --include "glb/food_*" --local-dir simready-glb
+```
 
-No mesh simplification is applied. The triangle drop comes from removed duplicate instances and helper geometry.

 ## Known gaps
 
 Physics, articulation and simulation metadata from the USD files are not carried over. Materials are converted to
 glTF PBR, so MDL-only shader effects are lost.

+## Changelog
+
+- 2026-10-29: 1,305 files carried a second copy of some parts at the origin, the USD instance prototypes
+  Blender imports next to the placed parts (for example the eyeglasses showed two pairs of arms). Those copies are
+  removed. Added thumbnails, the Dataset Viewer table and the 3D viewer Space.
+- 2026-10-28: first release.
