Could there be a “Twinmotion” export mode. In this mode, the animation data would be ignored (only because Twinmotion does not yet ingest Datasmith animation data).

Since Synchro Pro puts different materials on objects over time, perhaps the way around this in Twinmotion is to leverage the scene graph. Every phase of the project would be represented in the scene graph as a different branch with the correct objects showing the correct materials at that phase of the project.

Setting up the phasing in Twinmotion is relatively straightforward as it already has the concept of using the scene graph for phasing.

Possible issues:

Synchro projects might have multiple material changes in a single "phase", you'd have to probably set the material to the "I don't know what to do with this" material. This would force the user to make a decision.

Lack of translation and rotation of objects. Certainly the TRS of the object at the beginning of each phase could be used such that there is some perceived motion due to phase changes.
