I've had this for a while and decided to share it now.
skypk1 is basically sky1 with bright red colors, so I just photoshoped the 24-bit textured ones.
new
originalI also provided pkn5 sky textures, which is the same besides the texture being named sky2.
here is a suggestion if you downloaded the latest QRP. copy the sky1 textures and make a folder in your texture directory called pkn10. since the sky on there is named sky10, but its the same exact texture as sky1. you can also get the sky1 textures from the latest ezquake pak0.pak.
extract this zip into your painkeep/textures directory.
