KBT's Lockheed Electra - FSX native model - flies perfectly for me in P3Dv4 so would expect the same with the FSX model P-3. What difference does this latest addition make?
The fix for P-3C ORION was done as follows.
Editing for ORION in P3D
1. Change of lighting
There is no bug where the light source is shifted in P3D, so there is no need to fix it as a model part. Therefore, without applying self-illumination parts that require GMAX, I assigned effect files attached to P3D to CFG using coordinates.
2. Refixed the model again
Propeller spinner size correction.
Polygon coupling of engine nacelle (weld).
Changing the shape of the nose part of some models.
High detail of pilot model.
Addition of visibility parts in the static state.
In WP-3D, changes and additions of antennas and external measurement devices are added.
Abolition of reflection polygon parts (There is reflection setting in P3D)
Fixed bubble type window glass.
Includes DoorControl Gauges created by Georg Aubele. This gauge makes it easy to move doors, ladders and bomb bays door.
