I created a rather long object for FS2002. It was a course of gates in the sky. In GMAX I laid out the gates as I wanted them and them I attached them so they formed one object. When I fly about half way through, the whole thing just disappears! Is there a size limit for objects? Its odd...I can see the whole course in the distance, but when I pass a certain point it disappears into thin air. When I go into slew mode and back up, it all reappears. But when I go forward again, it vanishes. Any advice is greatly appreciated.Christine

Hello Christine,It seems that you are having a problem with visibility, V2 to be precise.You must calculate the correct (approximate, in this case) value of V2, and insert it in your calling macro or in the asm file.Please stop by the scenery design forum where you can obtain more expert help.Best regards.Luis
