Some Web Scenes are not displayed in the current ArcGIS Runtime 100.6

[Jan-Tschada]

We have a simple QtQuick application using ArcGIS Runtime for Qt 100.6 on Windows 10. The application queries ArcGIS Online for portal items representing web scenes. For some web scenes the "

LoadStatus::Loaded" event is raised and the scene view navigates to the area of interest, but the scene layers 3D features are not displayed. No exception is thrown nor any warning is logged.

Is it possible to narrow it down, e.g. create verbose logging output?

Sample Scene which is not working, but looks fine in the web-based scene viewer:

Hey Jan - you can hook into the layerViewStateChanged signal on the GeoView, but all that tells me is that the layer is not visible. I don't believe there is any additional logging you can enable. It seems like there must be an API bug preventing the layer from rendering.

Jan - are you able to run it through this tool to see if there are any issues with the data? Validate Scene Layer Package—Data Management toolbox | ArcGIS Desktop 

[Jan-Tschada]

When the SceneQuickView::layerViewStateChanged is raised, the layers state is NotVisible. The validate Scene layer package tool just found some warnings. Maybe I should recreate the multipatch features and try again.

I republished the web scene using different TINs for extrude between and now it works. Garbage in, garbage out.
