Thanks Dan, it worked perfectly. I just have one another question. I now want to fade the images in slowly when they are in the distance, hold them at 100% opacity until they are within 1000 pixels to the camera and then fade them out again. I can work out how to fade them in or out and adjust the point at which the transition starts and ends, but I can’t get both expressions to work when both applied to the object. One seems to cancel the other out. Is there a way to integrate both expressions into one?
Thanks!!
