I currently run with NMC as my base, then some ojo bueno textures over that and then a ground texture replacer. I dont remember the name of it. But ill go do that now and see what happens.
EDIT: Ok so I have found the culprit of what is causing the texture bug in the sky and oddly enough it was FNVRWL. I uninstalled every texture mod i had but it wasnt till i uninstalled that, that the issue went away. Now the dillema is which sky mod should i use? i very much enjoyed the look of FNVRWL so this is a major bummer.
