Hello,
I have panorama 6000x3000 and I use 3 levels.
I found that if I use FOV 70 аll tiles from the lower levels (1st and 2nd) and part of the 3rd level - current view - are downloaded.
If I use FOV 80 all tiles from 1st and 2nd level are downloaded. I can't understand why all lower levels need to be loaded? It costs me loading time and bandwith.
Is there any way not to load lower levels only level of the current view?
