It might help if you tell the wise men here what exactly you would like to have accomplished.
Rob, your comment seems to have an edge to it. I hope you found no reason to be offended by my question. I simply was seeking information on what had been discovered possible in fsx since my absence.
My concerns about fsx scenery design capability is pretty much what I've already asked, seasonal variation to both mdl files and terrain, and conditional animation, such as...having a hangar door open when the aircraft reaches a set location..or having a model rotate to always face the aircraft.
Now about how these were done in fs9, that's fully documented here in the wiki. The "wise men" as you describe them don't need me to tell them how to do this, they taught me. I've never used EOD, so I can't discuss that tool. I've only used GMAX for 3d objects since whenever it was written. FSDS before that. In GMAX animation is described in the user documentation, and converting that to conditional animation was the role for Arno's utility called "CAT".
Seasonal variants on objects was accomplished though a tweak to the ASM code, if I remember correctly. Seasonal variations on fs9 terrain was accomplished through a command line in the resample tool (if memory serves me correctly).
But....according to memory, all this was "broken" or overlooked when fsx was released, which was a great dissapointment to me. Then I went to Grad School so no time for fs anyway.
Now I'm reading the boards to learn what was learned since I dropped away. Your post could have represented much progress, however, if you hadn't tried these techniques in fs2004, then I understand that I got my hopes up without reason.
Can you advise why you wrote the edgy words in quotes above? I've reread my post to you, and it seems like the simple innocent question that I meant it to be.
Best,
Bob
