Objaverse Clean GLB

The usable part of Objaverse: CC0 and CC BY models only, broken files and fan art removed, ranked by quality, scaled to one unit and rebuilt as web, game and engine ready GLB with LODs, a phone tier and collision hulls. Every model names its author.

Each model keeps its own licence (CC BY 4.0 or CC0 1.0). CC BY requires credit: name the author, link the model and the licence, and say it was changed. LICENSES.md and metadata.jsonl carry all three for every model. Names and tags were filtered for fan art and brands, but the filter is not a legal review: check a model before using it in something you sell.

6015 models from Objaverse 1.0 by Allen AI, 16.12 GB of source files packed into 2.51 GB of GLB (web tier). Credit: Objaverse 1.0 by the Allen Institute for AI (Deitke et al., 2022, ODC-By 1.0), and the Sketchfab author of each model, named with a link to the model and its licence in LICENSES.md.

How the 6,015 were picked

Every object in Objaverse 1.0 went through these filters in order, each counted where it first failed: metadata filters, then the quality cut, then every file was opened and measured. Scripts: converters/objaverse in the CodePawl pack pipeline.

Step	Dropped	Left
all objects in Objaverse 1.0		798,759
not CC0 or CC BY (NC, NC-SA, SA)	90,448	708,311
fewer than 12 faces	9,271	699,040
over 400k faces or 10 MB	214,128	484,912
fan art of games, films and brands (by name and tag)	35,528	449,384
ripped or someone else's work (by description)	2,292	447,092
placeholder names (test, untitled, scan_01...)	8,802	438,290
unliked raw scans	7,076	431,214
below the quality cut (score from likes, views, staff picks, textures; 40 per author at most)	424,714	6,500
fan art, brands, real people, adult or hateful content, duplicates (caught in review)	397	6,103
absurd scale or broken positions	23	6,080
a picture on a flat card	6	6,074
stray vertices or wire-only geometry	1	6,073
missing or undecodable textures	1	6,072
would not draw or play in three.js (every tier tested)	57	6,015

Files

Folder	Size	What	For
objects/	2.51 GB	meshopt geometry, WebP textures	three.js, Babylon.js, any glTF viewer with the meshopt decoder
objects_ktx2/	3.55 GB	meshopt, KTX2 textures (ETC1S colour, UASTC normals), mipmaps	WebGPU and WebGL games: textures stay compressed on the GPU
lods/	4.14 GB	three simplified levels: 50, 20 and 6 % of the triangles	distance LOD, crowds, far props
mobile/	1.48 GB	25 % of the triangles, textures at most 512 px in KTX2	phones and light laptops
engine/	14.63 GB	no meshopt, no quantization	Blender and desktop engines that cannot decode meshopt
collision/	17.4 MB	convex collision shapes, plain glTF	Rapier, Jolt, PhysX, Unity colliders

metadata.jsonl has one line per item: title, kind, licence, authors, triangle count and the path and size of every tier. Its file_name is the engine/ file, so the Dataset Viewer opens each item in 3D and load_dataset returns it as a trimesh scene. Thumbnails are in thumbs/.

For web games and WebGPU

Load the objects_ktx2/ files for games: KTX2 textures stay block-compressed on the GPU (BC7 on desktop, ASTC or ETC2 on phones), so they take a fraction of the memory of decoded WebP. Switch to lods/ by distance and to mobile/ on phones. collision/ holds convex shapes for physics.

Measured on 12 items spread over triangle count. Phone page: 390x844 at 3x, pixel ratio capped at 2, CPU throttled 4x, network at Chrome's Fast 4G (150 ms, 9 Mbit/s), so phone load includes the download. The GPU is a desktop RTX 3060 and is not throttled: frame time shows the CPU side only, a real phone GPU is slower. VRAM is geometry plus texture bytes on the GPU.

Tier	File (median)	VRAM (median)	Triangles	Phone load (4G)	Frame time	WebGPU load (local)
web (12)	0.4 MB	10.8 MiB	11,088	576 ms	0.8 ms	22 ms
ktx2 (9)	0.4 MB	3.0 MiB	4,786	969 ms	0.8 ms	29 ms
lod2 (12)	0.1 MB	2.7 MiB	3,403	310 ms	0.8 ms	12 ms
mobile (12)	0.2 MB	0.8 MiB	4,252	333 ms	0.8 ms	7 ms

three.js WebGPU:

import * as THREE from 'three';
import { WebGPURenderer } from 'three/webgpu';
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
import { KTX2Loader } from 'three/addons/loaders/KTX2Loader.js';
import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';

const renderer = new WebGPURenderer({ antialias: true });
await renderer.init(); // KTX2Loader needs to know which compressed formats this device takes
const ktx2 = new KTX2Loader().setTranscoderPath('https://cdn.jsdelivr.net/npm/three@0.187.0/examples/jsm/libs/basis/').detectSupport(renderer);
const loader = new GLTFLoader().setKTX2Loader(ktx2).setMeshoptDecoder(MeshoptDecoder);
const gltf = await loader.loadAsync('https://huggingface.co/datasets/codepawl/objaverse-clean-glb/resolve/main/objects_ktx2/pony-cartoon-885d9f60/pony-cartoon-885d9f60.glb');

Use it in 67js

67js loads these files as they are:

npm install 67js@npm:@codepawlhq/67js meshoptimizer

import { Renderer67 } from '67js';
import { loadGltf } from '67js/addons/gltf';
import { MeshoptDecoder } from 'meshoptimizer';

const asset = await loadGltf('https://huggingface.co/datasets/codepawl/objaverse-clean-glb/resolve/main/objects/pony-cartoon-885d9f60/pony-cartoon-885d9f60.glb', { decoders: { meshopt: MeshoptDecoder } });
const renderer = new Renderer67(document.querySelector('canvas'), asset.parts, { ground: true });
renderer.render({ eye: [1.5, 1.2, 2], target: [0, 0.5, 0] });

Tested

Every file was loaded and drawn (drawn pixels counted) in each engine, three.js 0.187.0 and 67js 0.15.0, files from a local copy of this repository.

The 67js misses are 67js 0.15.0 refusing a whole file, not broken files: three.js loads all of them. Three causes, tracked in codepawl/67.js#496: a primitive with collapsed triangles and no usable normal, a node scaled to 0 (Sketchfab hides parts that way, often inside a clip), and morph targets without a base NORMAL.

Licence and credit

Objaverse 1.0 by the Allen Institute for AI (Deitke et al., 2022, ODC-By 1.0), and the Sketchfab author of each model, named with a link to the model and its licence in LICENSES.md. Each item keeps its own licence; see LICENSES.md and licenses/.

Changes made: Selected from Objaverse 1.0 by licence (CC0 and CC BY only), metadata and geometry checks and a quality score. Each model: empty primitives and one-frame clips dropped, bad values fixed, the scene put under one root that scales the longest side to 1 unit and stands it on y = 0 (original size and scale in metadata.jsonl), textures resized and recompressed (WebP, KTX2), meshes welded and meshopt-compressed; LODs, a mobile tier, an uncompressed engine tier and convex collision hulls added.
