I see the front middle pole should have a shadow coming toward the position you were probably standing in the ss, but it doesn't. I'd also expect the poles on the sides to cast wall shadows, but due to camera angle can't see them. Only other possibility is a secondary light source preventing the shadows. I know that sometimes developers in 3D do some crazy work with light sources to control different environments. It's possible there are hidden light sources that we can't see cancelling out the shadows. An example of what I mean is I've seen situations where it's appropriate to hide light sources underground to make it shine a bit more. Could be something like that at play.
