The animation pipeline supports the export of keyframed animation for hierarchies of nodes from 3D modeling packages via Collada.
For a given Collada scene the dae2json tool will export 1 or more animation clips from a single Collada scene along with the geometry and nodes which are to be animated by the animation. It is also possible to run the tool with a switch to export only the animation clips from the file, this can be used where the animations are modeled in multiple scenes within the modeling package, and hence exported to multiple Collada scenes. Animation clips can be exported to Collada scenes by setting them up with tools such as the Trax editor in Maya. Where multiple animation clips are present in the Collada scene multiple animations will be exported to the output scene with matching names. Where no clips are present in the Collada scene all the animations in the scene will be grouped into a single animation name “default” (can be overridden via a tool parameter)
