Will explain about why no ground service on this plane.
1. On P3DV44 or so , add-on like GSX are so good and doesn't really needed to do at this plane side.
So demand got less.
2. On FS2004 , it's coming from the unknown limitation of FS2004 model.
When making a plane , we creators use a tool (SDK) provided by the game's maker (It's open to everyone)
And if use as is , on FS2004 , maximum number of polygon is near 50000 even used carefully (Most of the case under 40000)
But A350 series is much more then that.
Our A350-1000 is about 136000.
More then twice of the size of maximum.
How we do is alike to Over 60000 polygon model for FS2004 tech, Lion heart made.
Explaining simple.
Show more then 2 models at once.
On A350 series , got too much and had to show 3 at once.
Most of the case Exterior and Interior model is a set so at this case so will be
Exterior1 + Interior1
Exterior2 + Interior2
Exterior3 + Interior3
Did that but caused a error.
If less polygon can make it thru.
And clear reason of this error is unknown (It only says Error to export to MDL)
So on this model had to develop a new way to make it thru.
Remade the whole model like under so that can use 2 and 3 a common parts between exterior and interior.
Exterior1 + Interior1
Exterior/Interior2
Exterior/Interior3
This made the total data size less and made the compile go thru
But still the exact reason of why this time went thru.
So decided not to include Ground services on this series.
It was before the -1000 so must have much larger number of polygons to use.
Also needs a extra space for the updates.
Really this A350 series was like challenge to the limit of FS2004 aircraft modeling.
If want to see how I shaved the number of resource on -1000 , there is a lot to live video on our facebook's page.
I feel many will feel crazy , just making few vertex define less using hours.
But all those made that super heavy fit in that tight space.
Please understand about the ground service.
