I am running into this issue where terrain I created using the smoove tool isnt casting shadows. I have selected the faces to make sure are set to cast and receive shadows, and they are receiving them fine. Is there anything else I should be checking?
To me, it appears the gentle blue bumps in the terrain are not high enough to cast a shadow.
Notice the curved seating in the scene barely casts a shadow.
I can almost guarantee there isn’t a problem, and that it has to do with the angle of the sun. Your sun is quite obviously directly overhead meaning regardless of how tall you make the hills, they won’t cast shadows as you’re expecting. This is due to the curvature.
Try changing the time to later in the evening and you’ll then see some shadows appear.
