I currently have a feature (auto play) slideshow with a series of thumbnails underneath, and i would like the corresponding thumbnail to change opacity (from 50% to 100%) as the main image transitions, to highlight which image is being displayed.
i have set it up using the 'states' with the settings as follows:
Mouse Down: 100%
Active: 100%, Stroke 1
As the images transition, the stroke appears around the thumbnails however they do not change opacity.
