Thanks ladynimue:-) Yes, Alekssander, booleans are primitives too, or at least made from primitives. Yves, sorry, but if you were a winner of Mover 4, you would not be able to use it, because it doesn't work with Vue 2:-). On the other hand, Vue 2 has no planets (Moon) included and as you cannot use "moon bitmaps from outside" on a sphere you have to use obligatory the Vue Moon from the planets... Guitta
