error: maxMemoryUsageInMB limit exceeded when resizing large jpeg textures

Describe the bug Resizing large jpeg textures fails with error: maxMemoryUsageInMB limit exceeded.

To Reproduce Run gltf-transform resize --width 512 --height 512 on a model with an 8192x8192 jpeg texture.

Additional context This seems to be an upstream bug in the scijs/get-pixels dependency. I opened an issue here: https://github.com/scijs/get-pixels/issues/57.

For folks running into this issue, the manual workaround for glTF files hitting this error would be to unpack the textures (if they aren’t already separate) and resize large textures manually.

gltf-transform cp input.glb output.gltf

The number of textures and size of textures both contribute to memory limits, with ≤4K being generally recommended. Aim for powers of two on each side, like 512px, 1024px, or 2048px. The textures do not need to be square.

Yes this worked for me, thanks for the response on Stack Overflow @donmccurdy, what I did, for anyone else interested, was:

1. Use blender to save a HUGE gltf as a ‘separate’ file (so the texture is separate).
2. Use Photoshop/Gimp to resize the texture.
3. Re-import into blender
4. Export again as an embedded gltf
5. Run npx gltfjsx ./myfile.gltf --types --shadows --transform --aggressive --draco https://www.gstatic.com/draco/versioned/decoders/1.4.1/ to squish it into a nicely sized glb file

When you do 5., the tsx generated might include a . in the file name, so either rename them in blender in step 3., or write typescript like so in the generated tsx:

type GLTFResult = GLTF & {
  nodes: {
    Mesh_0001: THREE.Mesh
  }
  materials: {
    'material_0.001': THREE.MeshBasicMaterial
  }
}

<mesh castShadow receiveShadow geometry={nodes.Mesh_0001.geometry} material={materials['material_0.001']} />
