Issue with glb model rendering in Android with filament and gltfio #3948

Closed udayk07 closed 3 years ago

udayk07 commented 3 years ago

Tried to load a glb ( model attached ) model using sceneform with filament. While trying to render app got crashed. I am using latest version ( v1.9.24) of filament and gltf loader.

Same model works fine in online gltf-viewer.

Could anyone check it and provide solution? Thanks in advance.

@romainguy

Found no specific logs other than above mentioned logs. Attached full console logs for your reference. ar_crash_log.txt

While loading the model in online viewer https://google.github.io/filament/viewer also model is not rendering.

I can reproduce with the native gltf-viewer. Besides all the empty vertex buffers, this gets printed as well:

This model is non-conformant; every accessor has its count set to 0.

This model seems to be generated by glTF-Transform so you might want to file a bug there. Since this model uses draco compression, the bug in the pipeline might be when compression occurs.
