Problem with Night Windows in Railworks???

[jpetersjr]

Here we see a skyscraper of my creation that I'm attempting to put night windows on.

During the night the night windows appear where they should be and can be seen from several miles away.

But during the day in Railworks the night windows aren't disappearing like they should and can still be seen there, where you should not be able to see them. There isn't a fx-day texture because the main windows are part of the texture which is part of the wall, so there's only a fx-night for the night windows at night. Is there anything I might have done wrong when naming the group and is there another way to do it.

Also, even when there was a fx-day texture the night texture still wasn't disappearing during the day and looked funny. That's why I never did anything with a night texture.

I want to start putting night windows on my buildings, but this problem has bothered me for months, if I can't get rid of this problem I'll just have to continue to do the buildings without night windows.
