Is this based on the master branch of the Draco repository, or the gltf_2.0_draco_extension branch? Maybe they're both in sync and tracking the same branch anyway, but I'm not sure and we may need to double-check.

Thanks Brecht – you mentioned earlier that you'd like to add opacity to the Principled BSDF node. I realize opacity and alpha are not the same thing, so just to clarify – do you still think there should eventually be an opacity socket on the Principled node? Or is mixing with the Transparent BSDF likely to be the long-term answer?

@Bronson (DBAGibbz) could you explain what the Blender screenshots mean? The 2.79 and 2.80 screenshots are after importing this GLB file into each version?

About glTF export/import losing roughness - roughness is supported, and will be stored in the G channel of a shared occlusion/roughness/metalness texture. There may be some issues merging textures on export, although I think much of that has been fixed recently. See the suggested node structure in the in-progress documentation: https://developer.blender.org/D4082.
