Amplified World: Disable sky change?

[SPoR]

A few months ago I made a server with the amplified world and several mods. I currently have the main base on top of one of the mountains at about y = 230. I recently installed Galacticraft only to find out the sky is split between blue and black due to the high altitude. Is there any simple way to change or prevent this from happening on my server?

Thanks
