Thanks mate. You got me on the right line of research. After some trial and effort, I found that these were the appropriate corrections:
fuselage Insignia
[Decal001]
MeshName=fuselage_back
DecalLevel=0
DecalFacing=LEFT
FilenameFormat=Insignia
Position=-4.800,-0.118
Scale=0.95
DecalMaxLOD=3
fuselage Insignia
[Decal002]
MeshName=fuselage_back
DecalLevel=0
DecalFacing=RIGHT
FilenameFormat=Insignia
Position=-4.800,-0.118
Scale=0.95
DecalMaxLOD=3
Changes from my initial post (the standard skins)
- MeshName=from Line05 to MeshName=Line05
- Position=from -3.700,-0.120 to -4.800,-0.118
End result: Stars and bars!
