Recently I used the plugin to switch between different pre-rendered finishes, inside a 3D scene and calculate costs. I used different views of the same product also I was able to display only the specific fpd-category for each product. Large list of methods and events. Very organized and complete documentation.
Fancy Product Designer is high quality software you can't find anywhere else in terms of breadth of customizations and depth of connnective features on the back-end. I don't think there is a product that CAN'T be customized with this software!
