MDL Merge
(Ideally the cables would be smaller)
It turns out that it's extremely easy to both rotate and rescale MDLs with MCX (Transform object).
So that the cables fit, I reduced the scale to .66666 and rotated +5 degrees, I then changed aicarriers.cfg to;
[formation.x]
title=Hermes STOBAR
unit.0=Hms Hermes, 0, 60
unit.1=FLOLS_TrailerH, 43, 105
unit.2=ArrestingGearH, -6, 75
I also had to change the sim.cfg height to;
static_cg_height=54.87
Even better, with the development release of MCX it's possible to merge MDLs!
Import Hermes, then click Merge Objects,
Load object , ArrestingGear67pc5deg.MDL
enter offsets (In meters)
X offset: -6.00
Y offset: 15.00
Z offset: 16.80
Merge
Export.
Done!
You can now delete
unit.2=ArrestingGearH, -6, 75
These numbers are guestimates and I've only tested it briefly, but it all seems it work ok.
