Hi
Thanks for your suggestions!
I tried that before with the hotspots (mostly for video overlays) but it was always a lot of work and a little hassle.
Loosing the ability of multires also can become a problem, so therefore I was think as layerd panoramas with transparency.
i also do it like you, i render all combinations .-)
it takes a lot of space but the hotspot way is probably more work.
Good to hear, so maybe we have to stick on that solution. Do you have examples to show? Would be interesting to see how you did the interface for that.
