How to control the transparency for an hotspot group

  • Hi to all!
    I'm really a beginner, so sorry for my question:


    I've learn through the forum how to "group" some hotspot and I've learn also how to control the transparency (in relationship to the point of view) of a single hotspot using this code:

    Now I need to modify that code in order to control an hotspot group...Someone could help me?
