I'm testing GLTF files for a web based AR experiment and have to say, really impressed with the sketchfab exporter for Unity!
I am running in to a little trouble however with a complex animation drawing from this Unity asset package.

I think I may be trying to do more than the exporter currently supports, but still would like to double check since it would be a revelation for A-Frame/ARjs development if it worked.. Anyone know what's going on with my export?
