Hello guys, I cannot guarantee this but usually if the aircraft cannot be accessed in the QMB it can be a texture issue, the mod is trying to find something
that is not in its own folders and cannot be found elsewhere.
The log will normally tell you if this is the case as it will tell you what the texture is that the mod is looking for, as with most issues this generally is at the
bottom of the log, most times it will be that the mat files call up a tga that is stored in the game texture folders, if you know what the texture is then
usually you can find it in another mod. Sometimes a pilot or glass tga will be missing for the pilot model, experienced this myself a few days ago testing a
new plane
Personally anything I release I like to include all the necessary textures with the mat file picking them from the plane and cockpit folders, others do not and it
can lead to these issues.
Take care and be safe.
Wishing you all the very best, Pete.
