Different Backgrounds at different daytimes

Hey guys,

I didn't find a similar thread to this, so I open a new one here.

My idea is to use different battlebacks. I found some very impressive backgrounds, the problem is you can see the sky...
In the game are different daytimes, so it looks weird, when I use a battleback with a shining sun although it's nighttime.
Is it possible to change the backgrounds with progressive daytime?

I would be very thankful for an answer.

Thank you very much in advance!

Best regards,

Hargatio

Essentials already does this with Field - FieldEve - FieldNight etc
