Not sure I understand what you mean?
I have made an animated object in 3DC and exported it to Rail Simulator.
Just select the root object and export the IA-file just as you export the IGS-file.
My object had two keyframes with a rotation between, the one IA-file contained that info.
Later in the Asset Editor the IA-file was specified in the blueprint.
Hope something of this makes sence to you.
