glTF Sub-Models or Parent/Child Grouping

Is it possible to
interact with a sub-model of a glTF or create a parent child link / group?

Case Sample: Use CZML to drive the path of an
airplane while using additional CZML with orientation data only to rotate wing elevons.


Currently, you can’t target a glTF node transform from CZML, but this is something we want to support. There might even be some prototype work at AGI.

In the meantime, you could use a glTF keyframe animation, which uses the same Cesium clock as CZML, or you could use the Cesium API (with primitives, not entities) to change the transform like this example.
