This could mean (a) that your model size is mostly things other than geometry, which draco doesn’t affect, or (b) that the model is non-indexed which `gltf-pipeline` can’t compress. see [Draco option having no effect · Issue #420 · CesiumGS/gltf-pipeline · GitHub](https://github.com/AnalyticalGraphicsInc/gltf-pipeline/issues/420).
