Answered at FS Developer.

Briefly, to recapitulate...

The "root node" is like the root of any disk... it is the lowest level folder...

All aircraft models must have either "exterior" or "interior" as the top, or "root" node name. All other objects in the scene are Linked to that node.

Code:
exterior
   engine
   fuselage
   wings
   etc.

Nah, I never Use the Verify in exportLOD tool,I don't even rename names like "Right Wing or R_Wing, L-Flaps_01 Nah nah.(This is not FS9-SDK anymore). I leave as it is Lines,Object Box chamferbox etc, All I do is LINK what needs to be link , create the animation and make it work fine in FSX ..

But I guess that's me I'm a little bit a mess

By the way you haven't set the friendly name ,won't export like this ,Hit Create "it will make the Gui code" and then hit edit and put a name like "Kevin" or anyname the name of the model..

Basically you have to set a link hierarchy for all your parts... to define which are attached to which (as in, ailerons attached to wings, and other parent/child relations such as that)

Please, Alex...

I'm trying to teach folks how to build an FSX model that can be easily "downconverted" to FS9...  Wink

Yes, you can cross the street anywhere you want; just don't be surprised if you get hit by the bus!

Pedestrian crosswalks are there for a reason.  Likewise, following the SDK conventions for "part names" per the FS9 SDK even while building for FSX is just a smart thing to do.  Cool

Yeah, Embarrassed I'm a person without discipline and order , and I'm planing to release a bit later after fsx release the two citations in FS9-sdk ,Of course I have a bigger problem about the gauges  Embarrassed Undecided
I'll post something about it

i would link that fuselage part to a dummy (call it exterior), so the dummy is the top node... this way, you can put the dummy at position 0, 0, 0 and move the aircraft about if you need to

makes for greater flexibility  Smiley

Well, since it's required for FS9 models, I would too just as a matter of habit...

Can you explain more how to set up a dummy part?

There are two methods, Kevin.

1. Use the Max/GMax "Helper/Dummy" to create a Dummy object and place it at 0,0,0 in the scene. Name the part as required.

2. Create a tiny planar object at 0,0,0 and name it as required. I typically will rotate the part so it's face is down, to there's absolutely no chance it will ever be seen.

Understand that any animated parts atttached to a true Dummy (a la #1 above) will lose all animations when compiled. For this reason I stick to pseudo-dummy objects a la method #2.

For convenience, I have a defalut hierarchy set of 'pseudo-dummy' objects which I can Merge into any new project. Any additional 'pseudo-dummy' object needed can be cloned from them quickly.

For this purposes, then will it suffice for the dummy object to have only two points (therefore no polygon to even be remotely visible) or MUST it have at least one 3-point face?


(Note - Rhetorical question, for discussion, since I have the habit of making a very small hidden "cube"  as any dummy object I may need)

The simplest geometric object allowed is a triangle, which by definition has three points...

So I actually name the part 'Dummy' then?  I did that the named the fuselage 'exterior' and the cockpit tub (wich is at the top of that hierarchy) as 'interior'

No the "dummy"  part is the function.  You would name it "exterior"  or "interior"  (when modelling for FS9).

When modelling for FS-X, since you create and compile a separate model/scene, you can keep the convention, but otherwise ....  name for convenience.
