The eagle nebula is one of the more realistic custom sky texture packs currently spreading across the internet! Within one week of launch it had already been downloaded over 1,000 times! It helps create a sci-fi realistic atmosphere and can be wonderful for both movies and space themed environments! So what are you waiting for? download the pack right away!
NOTE: The newer version of optifine breaks older custom skies! I have updated the eagle nebula to be universal so it works with both the old versions "and" the new versions of optifine!
