Hi, I am trying to find a way of fading the ends of a sweep object, that animates like a ribbon. If you look at the attached I need each end to be faded to zero, but I can’t work out how to do it so it follows the animation i.e. the ends stay faded on each side as it animates. I thought a linear field but how can I get it to follow the ends of the animation? Confused!
Any help much appreciated
