Blender object invisible in Standalone player

Hello,
I am building a VR app on from command line:
"C:\Program Files\Unity\Hub\Editor\2019.3.7f1\Editor\Unity.exe" -batchmode -buildTarget Win64 -projectPath d:\a\1\s\proj -logfile d:\a\1\s\Logs\UnityBuildLog_2020-05-24-18-55-57.log -nographics -executeMethod AzureDevOps.PerformBuild

and some blend assets are not rendered correctly.

Building the app from Unity Editor does not have this issue.

Any idea why?

 

I had to export to OBJ and reassign materials...
