No, they are closed in that picture, if they were open you would be able to see trees and the parking lot.
If the windows were open you would be able to see the trees and parking lot and stuff. In the game it's hard to see because the camera is so low but the windows are open in the game because you can definitely see the blue sky. The window panels are translucent so light still shines through them when closed. See below, in the first 2 the windows are open, in the 3rd one they're closed.
I've made note of this in my stadium accuracy notes.
When the roof at miller park is closed the window panels should also be closed but in the game the window panels are open which makes it feel like the roof is open even though its closed.
Yea, I noticed that too. But in a later stream Ramone was asked about it and he said the he had a convo with the stadium guy for Miller Park and they said they were going to fix it and have the panels closed with the closed roof.
