Check and shrink the .glb, .gltf and USD models a three.js page loads - size, triangles, textures, Draco, meshopt and KTX2, a verdict for a website or Shopify, a smaller copy with WebP textures. Use for a large model file. paprika3d's model_audit tool.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Check a three.js page's model files
`model_audit` needs no page open: `path` is one file or a folder (the whole project when left out), read from the file itself with no decoder. Each file gets its megabytes, triangles, materials, each texture's size and format, and whether it uses Draco, meshopt and KTX2, then a verdict against `target`: `site` (the default: 4 MB of assets, 200,000 triangles, 2048 px textures) or `shopify` (a GLB of about 4 MB, textures at most 2048 px on a side).
A failing file's reply ends with the `shrink` call that fixes it: `shrink: { textures: 2048 }` caps each texture at that size as WebP, `textures: false` drops them; every triangle is kept. With the page open, `look { save: "before" }` first, then shrink, point the page at the new file and `look { compare: "before" }` (`../threejs-game/references/assets.md`).
If `model_audit` is not among your tools, the paprika3d MCP server is not installed: it runs as `npx -y paprika3d serve` (stdio), and https://paprika3d.com/docs/install has each agent's line.Read the whole file at its exact version.
How to install
mdr add paprika3d/paprika3d/threejs-glb-audit@sha256:b029663d9e371cf7The line at the top of this page pins the label git:20261029.bed5213, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
