Hi Robert,

> Are there plans to get theses in next version?

Currently they aren't supposed to just be totally ignored, they should get exploded into regular geometry.

If you have a STEP file where things are just not totally showing up at all can you please send that to me at moi@moi3d.com so I can take a look?

It is true that the hierarchy will not be preserved though. Currently MoI just does not have an instancing mechanism in its own infrastructure to map these to. I do plan on implementing an instancing mechanism in MoI in the future, there is plenty of work involved in doing that so I'm not entirely sure when it will happen. Maybe sometime next year during the V4 development period.
