I don't know why ,If people knew how dificult this is ,even the most expert could take
several month to make a single model,Most of them join in groups ,one for texture other for
gauges ,this is not easy ,and its though to learn ,few moth ago I though FSX-SDK was tough
and absurn..I was Wrong ..
Today I realize its indeed more friendly with the animation ,the exportations are
instataniuos ,Not like the makemdl9 ,every exportation could take an hour ,and this is about prove and fail game ..
Practicly what you see inside Gmax its what you get ,Diferent than FS9-SDK witch you did have to export more to see if what you see (Animation) work fine in the game..and wait for hours for that ..
there is a beutiful Dialog between gmax and the plugins FSX-SDK having a better effects and more features..
What I don't like of FSX-SDK. its the vulnerability of the mdl format there is a freewaresoftware that is being use to hack designers model encripted under modeldef.xml.and it came in two diferent parts interior and exterior wich any VC can be use as if it
where a 2d panel, a 2d panel can be made in 2 hours while a VC can take at least a month
,Frtuanly the Team including Bill Leaming developt find a way in a code wich the VCs will be useless without the plane Like an attachment recently and I apply..very effective
I apply into the 707 VC this is what they will find if this VC in place in another aircraft

Unfortuanly this is a matter of time when some one find this vulnerability of FSX-SDK MDL models import the mdl and do anything they want with others work ,Like one those heroes call "airplane fixers" wich for me are just pirates and Poor hackers uncapable to to doo their own aircraft or sceneries..
