Once made LOD for my worldspace I have water missing in some cells: http://s1295.photobucket.com/user/PelinalWhitestrake/media/2013-03-24_00002_zps27c2fea8.jpg.html#/user/PelinalWhitestrake/media/2013-03-24_00002_zps27c2fea8.jpg.html?&_suid=136415644124008593077785844663 and on the map: http://s1295.photobucket.com/user/PelinalWhitestrake/media/2013-03-24_00002_zps27c2fea8.jpg.html#/user/PelinalWhitestrake/media/2013-03-24_00001_zps67348937.jpg.html?&_suid=136415644124008593077785844663
But when I get closer water appears where it should be. So I guess it's a LOD problem isn't it?
