[solved] no shadow on geometry

I have two directional lights in the scene, all with the shadow type set as soft shadow. However, I only got the shadow of the geometry cast on the ground surface. The shadow on the building casted by itself is not shown at all.

May I ask how to correct this?

Thanks!

… it seems there’s a boundary in the camera view beyond which the shadows casted on objects will not be rendered. (see image below)

Can anybody advise if this can be disabled?

Thanks!

OK, I found the answer from
