Submit models with animations

[scurest]

Collada only (functionally) supports one animation, so you'd need to concatenate the animations together end-to-end into one before you export. For an imported glTF, that means open the NLA editor, unlock all the tracks, move all the actions into one track end-to-end, star the track, and bake it to get a single action. Then you should be able to export to .dae.
