Hello,
Just got Reno pack and found L-39 cockpit camera position too low and too far in ejection seat. Here is values I found to try fix this. Just change your L-39s cameras.cfg line with this one
eyepoint = -16.185, -1.3, 3.50 ; (feet) longitudinal, lateral, vertical distance from reference datum
Default pos is really bad especialy in VR. This looks more real to me. Just compare real photos or external view where pilot head is in relation to seat headrest.
Hope it helps L-39 pilots.
