I have stopped testing with TpotS (The Path of the Shell) export as it has an issue with exporting ladders and losing properties when in a compound parenting situation.
I am now able to test exporting as MOULa and testing with Destiny it seems a more consistent in its behavior (The ladder tool works and it appears not to lose collision effects when objects are parented).
I have yet to try an Ages Beyond Myst export probably because I am not sure what that is and how to test it.
