In a separate Twinmotion thread, there was a question touching on version control / display of design iterations within TwinMotion. Figured I would start a thread for those who would like to specifically discuss this topic.

In your example, you would turn the design layer for version B off and export only the visible design layers to C4D.
You would then turn version A off / B on
