Hi.
JanHas made only external models and wing model from cockpit view. His models did not changed the Cockpit files, or the pilot model in the cockpit.
You can find the default pilot texture in the following path (if you change this the pilot texture will be different only in cockpit view):
\Falcon BMS 4.34\Data\TerrData\Objects\KoreaObj\8018.dds
(the 8019.dds is change by Weapon Delivery Planner, not worth to change it if you use WDP)
