I have a client that wants to have scenes launched from links on a separate floorplan and then when the tour opens have all the scenes displayed within the tour viewer by small jpegs.  This building will probably have a couple of dozen or more scenes.

What is the best way to arrange tours this way?  I initially thought the easiest way to use the floor plan is the have separate tourweaver instances created for each scene for each link (room) on the floorplan but then how do I link everything together into one viewer? 

How can I change the start scene for the tour?  That way I could have all the scenes in one tourweaver instance and the link from the floorplan would just open the various scenes based on which one was clicked.  The user could then click on the small scene icon within the tour viewer without having to navigate back to the floorplan page.  Thank you.

Really late answer...but anyways.

Try using Flash like I did in this multi level tour.
