Because its a lot of work ...and I can not stop what I am doing to work on it at the moment. More resolution, new textures and new lighting effects. It's @150 px/meter...there's lots of room for improvement of that number and higher resolution means painting new rivets, new lines, new grunge, new spec map, more textures, more layers, more time, etc etc etc...so much to do. No worries, but I've been busy bringing all that to xplane 10 for the last 2 years Leen! (As much as Lamianr would let me anyhow) I develop flight models / 3D models / UV Layouts/ Textures / 3D object library / Custom Scenery / Plugin programming and well.....I'm just a busy guy. -Tom
