Filament incompatible with sanctioned glb models #2443

Closed tellypresence closed 4 years ago

tellypresence commented 4 years ago

As mentioned on khronos site, the kenney models "tower defense kit" fail to load due to filament error, e.g. for towerRound_sampleF.glb:

 E/Filament: Unable to parse glb file.

with throwable CompletionException:

java.lang.IllegalStateException: Failed to load gltf

Thank you. As mentioned in google-ar/sceneform-android-sdk#1055, the asset you mentioned is non-conformant (doesn't follow the glTF specifications) and that's why it is rejected by our validating glTF parser.
