I tried using code:
<panoclip>.pano.addHotspot(<id:String>,<pan:Number>,<tilt:Number>,<mc:MovieClip>);
under AS3 and it generates an error. It works fine under AS2. I'm I doing something wrong?
I guess the problem is in your code. I have used the method <panoclip>.pano.addHotspot(...);, it works ok. May be you try to call the method before loading a panorama.
