Hi Umberto:
Don't really know if this was asked before, but as you probably know, there is a lot of noise at Avsim and LM forums regarding P3Dv3.3 non-compatibility with previous ground layering system that are/were used by addon scenery providers. This is applying to certain scenery, like ones from UK2000, LatinVFR, Taxi2Gate, and also to some scenery from Fly Tampa and Flightbeam (just from memory from what I've read in those forums). Want to know what to expect from FSDT scenery, since I have almost all of your products actually installed in P3Dv3.2, before I make any upgrade to v3.3.
Thanks,
Ed
