Mr Rodeo sir, I have a question. Even if you are only doing "fly over" scenery, downloaded at level 3 from FSET, do you still make tiles in Geoconvert up to level 13? I normally do levels 9-11 at that resolution. Should I do 12 and 13 as well to avoid any problems like pop-up?
The question is, what are you geoconverting on?
If you're geoconverting where there's nothing but raw satellite low res photo, then no problem limiting your geoconverting to level 11.
If you're geoconverting where there's already some aerial photo scenery (e.g. DLC), then you'll need to compile in high enough levels to prevent the underlayer to pop up... there's no clear priority setting in AFS2, unfortunately.
