Open street map building don't cast shadows in raster mode

Reproducible with cascaded and virtual shadow maps.

Seems to be a regression from 2024.1.2.
All TM 2025.x version have this issue.

1 - Populate the TM scene with the Urban tool

2 - Observe the shadows cast by the buildings

 

Result: The buildings don't cast any shadows

Expected: The buildings should cast shadows

Workaround is to select all buildings, enable the modeling tools, do any non-destructive modification, such as Auto fix normals, and apply. The meshes will be regenerated and correctly cast shadows.
