Question
So my CSGBox3Ds cast no shadows with factory-default out-of-box worldenv/sunlight/render-settings and their Cast Shadow set to On:

Right now I'm doing this course where the instructor has 4.1 on Windows and there the CSGBox3Ds are casting their shadow:

Might there be an obscure non-obvious setting in Project Settings I have messed up? Because under Rendering / Lights and Shadows every setting just has its default value.
Wondering if obscure 4.3-4 bug or gfx driver or HW bug.. do your CSGBox3Ds cast shadows?
