hi, in the examples page ...... https://krpano.com/tours/weingut/
that pano, the 'door opens on rollover' effect (or curtains in this case) i would buy krpano to achieve this effect (it is not really an option in my current software) , but what is it called (so i can search for it here) I would like to find some talk and examples about it on this forum.
any ideas, links?
thanks.
