Just getting started with WebScenes so no expert level knowledge here.
What I have is an Autodesk Civil3D file containing solids.
Converted those to Multipatche featureclasses in a file geodatabase using FME Desktop 2018.
In ArcGIS Pro 2.3.1 I created a local scene and imported the Multipatch featureclass. This works great as shown below.
Next I used "Create 3D Object Scene Layer Package" to export a .slpk and Uploaded to ArcGIS Online.
Published to Hosted Scene Layer. This time the result is not what I hoped for.
Using "Validate Scene Layer Package" I tried to understand what went wrong. The log:

END OF VALIDATION REPORT
Did google "extends outside the mbs of its parent" but only found my own question on SE. I suspect it has to do with the proportions of the objects and the level of detail, but did not trip over guidelines. Somewhere in the model the more compact objects visualise correct where the long objects don't.
What am I doing wrong and how do I solve this? Thanks!
***update 2019-03-27***
Added file geodatabase with multipatch featureclass to test.
