I have 2 SU files.
The 2nd is a copy of the 1st file with some adjustments in geometry.
But in the 1st file the shadows in plan view are visible on the wooden floor of the interior.
In the 2nd file not… And I can’t find what is going wrong…
See attachments
1st file with correct shadows visible on floor, not on ground outside
Interrogate the “floor” via Entity Info
Presumably the floor geometry is grouped.
Confirm the group and all faces within its context have the desired Receive Shadows settings.
