Hey @aldinss and welcome to our forums!
It’s difficult to say what exactly might be going on here based on this image, but I suspect the rect lights you’ve placed, might be too close to the geometry that is supposed to block the light, and that might cause the missing shadow. You could try either moving the light source a little or add additional geometry (behind the wall, so you wouldn’t see it from this perspective) to make sure the ceiling doesn’t receive any lights.
Optionally you might want to try the ray-traced artificial lights feature, this should give you the advantage of:
more accurate (ray-traced) shadows
the option to model this kind of light setup just with geometry with a self-illuminating material instead of rectangular lights.
Thank you very much sir. Adding additional geometry fixed this issue. All the best!
