Morph target / blend shape problem with draco compression #103

Open williammanco opened 6 years ago

williammanco commented 6 years ago

Hello, there seems to be a problem with the draco compression, if I convert the model from fbx to gltf with the "draco" compression, it breaks the model, while without compression everything is ok.

tested with gltf viewer https://gltf-viewer.donmccurdy.com/ I attach the gltf models

Thank you for the report, and for the test models! I will look into this soon. It would be easier if I had the FBX -- are you at liberty to share that? If not, I will do what I can without. :)

@zellski I converted the original model (by mirada from rome) from .blend file to fbx.

Hi -- also running into this issue. @williammanco blendshapes work if i use gltf-pipeline to convert normal GLTF output of FBX2glTF to draco.

This bug makes me sad, but realistically I won't get to it soon. If you can recruit someone to help out, I am happy to accept pull requests.
