Finnair OH-LXA reflecting the configuration circa. 2017-2018 (see IRL: https://www.planespotters.net/photo/843619/oh-lxa-finnair-airbus-a320-214).

This is a unique livery because this aircraft features a non colour matching grey cowling on the RH engine (see link above). 
It also features some other differences compared to other current airframes, such as the OneWorld logo being aligned with cabin windows.

Features:

• - Custom cabin seats
• - Adjusted PBR textures: IRL, the "FINNAIR" decals on the tail and fuselage are very dark, but turn into a shiny dark-blue when hit by direct light. 
• - Adjusted dirt and weathering. Especially for the main wheels (carbon dust from the brakes) and the engines cowlings.
• - Custom aircraft configuration: DDRMI, no brake fans, selcal AF-MS.

(optional) If you prefer having both engines white:
method 1:  you can delete both files named A320_CFM_R_ALBD.PNG (one is a .dds, the other is a .json). The RH engine will then revert to the default white engine texture.

Method 2: you can also replace the RH (grey) with the LH (white) side texture (copy A320_CFM_L_ALBD.PNG, and rename it A320_CFM_R_ALBD.PNG). By doing that, both engines will  also be white but the RH engine will have extra weathering that is not present in the default white engine of method 1. This extra weathering consists of that yellow-ish dirt (oil, fuel...) around the reversers. You can see that on IRL photos of the aircraft.

Please do not hesitate to provide feedback.

If you notice an error or if something is missing/could be improved, I will be glad to update the paint.
