I downloaded the Star Wars DeathStar hanger, might i say very well done. My problem is when I render an animation of a ship entering the hanger it only renders the reflection of the ship on the floor once. The reflection does not move with the ship, it just renders the relection of the ship on the floor for the first slide. In the picture below, you will see what I am talking about. [image=http://i53.photobucket.com/albums/g66/espzero/reflecprob.jpg] Circled in red is the relection of the ship at the begining of the animation. This shot was taken at the end of the animation after the ship had come into the hanger and landed. Can anyone help explain this? How do I make it so the reflection is rendered throughout the animation?
