Incorrect positioning of cast shadows. Standard shadows fall to the right (east) side of the object itself, as if the light source is to the left (west). In your case, judging by the preview, the shadows fall at a different angle (to the southeast, supposedly the light source is in the northwest).
Didn't you notice that?
Also, the shadows from closed gates look as if the gates are open.
I appreciate your attention to detail and thank you. The shadows for the IR3 walls and gates are very similar to the shadows of vanilla walls and gates.
There is no issue here that I can correct.
