I have to say that using FSDT KJFK with MegaScenery Earth City Pack is really nice, but unfortunately this photo real scenery causes problems at the airports. Since I have FSDT KJFK, I'll direct my question for this area, but in reality I'm having more issues at the KLGA airport from Imagine Simulation. Now that I've installed MegaScenery Earth for the entire NY area, I'm having elevation problems. In some areas I get MegaScenery to bleed right above the airport surface, and in other areas of the airport the planes and objects just simply sink into the ground. I've made sure to keep the airport sceneries at a higher priority than MegaScenery, but that doesn't work, and I've read from some other forum that photoreal sceneries in FSX does't work like they used to in fs9 when you are trying to set priority levels.
Any way, I know MegaScenery is not FSDT's problem, but if anyone here is using both of these products, and have had problems with this, please let me know how you have solved it, or suggestions on how to solve it. Unfortunately MegaScenery doesn't have a forum like we do here to discuss these issues.
