[danger]

other thing which disturbs me is the 'very yellow' reflection on the fuselage when youre firing your guns, but I got no clue how to change that, would welcome some help...

maybe its the brightness of the muzzle flash itself ???
i use the updated version of the plane shine mod, and a metalic skin. perhaps that is the issue ?

You see the same coloring inside the cockpit too, when the muzzleflash itself isn't visible.

Avala's planeshine mod doesnt influences anything except the reflections from some angles.

hmmm ????? maybe try reducing the flash brightness ? and if u need beta testing on ur mods i am more than happy to help you.
