Well if people was wondering how to get Fog sky i just did this awhile ago and i hope you guys will appreciate this :D
Firstly add
Than findCode:public boolean fog = true;
Above that addCode:worldController.method313(xCameraPos, yCameraPos, xCameraCurve, zCameraPos, j, yCameraCurve);
PictureCode:if(fog) {
DrawingArea.method336(503, 0, 0, 0xC8C0A8, 765);
}
