+# SimReady GLB
+
+Web-ready glTF binary (`.glb`) copies of the 3D models in
+[nvidia/simready-assets](https://huggingface.co/datasets/nvidia/simready-assets). Each file loads directly in
+three.js, Babylon.js, model-viewer or any glTF 2.0 viewer.
+
+Models by NVIDIA SimReady, licensed CC BY 4.0. This dataset converts and compresses them. It does not change what
+they show. If you use these files, credit NVIDIA as the original author and link the source dataset.
+
+## 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.
+
+| | Blender export | This dataset |
+|---|---|---|
+| Total size | 224.9 GB | 3.8 GB |
+| Triangles | 777M | 564M |
+| Largest texture edge | 4096 px | 1024 px |
+
+Example: the V8 engine (`engineAssembly_v8_engine_a01`) is an 888 MB glb out of Blender and 9.3 MB here. Its first
+frame in Chrome took 9.4 s before and 0.57 s after.
+
+## How the files were made
+
+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`).
+
+No mesh simplification is applied. The triangle drop comes from removed duplicate instances and helper geometry.
+
+## Loading in three.js
+
+The geometry uses `EXT_meshopt_compression` and the textures use `EXT_texture_webp`, so set the meshopt decoder:
+
+```js
+import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
+import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';
+
+const loader = new GLTFLoader();
+loader.setMeshoptDecoder(MeshoptDecoder);
+loader.load('engineAssembly_v8_engine_a01.glb', (gltf) => scene.add(gltf.scene));
+```
+
+## 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.
+
+The conversion scripts are in
+[codepawl/3d-builds](https://github.com/codepawl/3d-builds/tree/main/works/2026-10-28-simready-showcase/batch).
