I installed Morrowind Overhaul 3 and I freaking love it. BUT: The sky at night is a bit too colorful for my liking. Can I just change the textures for the sky at night?

Which mod would you recommend for a decent (not too over the top) sky?

Should I even think about installing another mod on top of Morrowind Overhaul or is this likely to [censored] things up?

Yes you can. I use Misty Moon's but I think you would want only sky textures and not have to pick through an entire pack for them.

You may like Vurt's Hi-res skies and weathers pack for SWG's skies.

Many use Morrowind Overhaul as a base and then install mods that were not include in the pack as they were without author's permission, or were overlooked, or just more recent.
