I actually end up getting this working with my model and being able to load the model in three.js with donmccurdy's work in https://github.com/donmccurdy/three.js/blob/feat-gltf-draco-extension-v4/examples/js/loaders/GLTFLoader.js . It turned out that I had some bad meshes in my scene with 0 verts which three dealt with fine but were definitely incorrect. Fixing the exporter to strip those (and subsequently fixing the model), corrected the issues. Thanks! |

This work compresses a glTF 2.0 asset according to the KHR_draco_mesh_compression extension. Currently it's only tested against mesh compression only. Working along with other optimization methods is temporarily disabled.
Please follow the gltf-pipeline guideline to install the repo and use the following command to compress your glTF 2.0 assets.
Example:
node ./bin/gltf-pipeline.js -i ./specs/data/Duck/glTF/Duck.gltf -d --draco.quantizePosition=10 --draco.quantizeNormal=8 --draco.quantizeTexcoord=8 --draco.quantizeColor=6 --draco.quantize Skin=12 -s -o Duck.gltf
