"Install Advanced Painter action item (found under 'Painter' category) to your toolbar, main menu bar, or quadmenu. Please refer your 3ds max documentation for more information on action item installation."
I understand that this "action item" links my script with a toolbar tool, so I can set it. The problem is, that in 3ds max help I cannot find any mention about "action item". Nor in google. Maybe it is some other thing, that author named that way?
I don`t know what to do, to make it work. This is very important to me. Can anybody give me a hint, please?
