Export .slpk from ArcGIS CityEngine and Missing Textures in AGOL

[MCh]

Hello all,

I have built a model in Sketchup and  bring it into CityEngine 2023.0 in .kmz format, everything looks fine and correct in CityEngine as in the first picture.

However, after I export these static models from CE into .slpk format and add item in ArcGIS Online.
By visualize in Scene Viewer, I've notice that only model's faces that applied default colors in Sketchup are missing. Only texture that use image appeared.

My issue is quite similar to this topic 
https://community.esri.com/t5/arcgis-cityengine-questions/obj-missing-textures-in-cityengine/td-p/73...
But my texture missing in Scene Viewer not in CE.

Is anyone know how to solve this issue?
Thank you in advance.

Hello @MCh 
thanks for bringing this up. SLPKs have a level of detail LoD structure to dynamically adjust the detail depending on the viewing distance. It indeed looks like the untextured faces (with only vertex color) are not shown. For further analysis, would you be able to share the scene layer you created?
