Low quality texture.
This is just my opinion, but I would go with more higher texel density for the texture EXT and cockpit, maybe PBR will help but right now is a little bit flat and more cardboard.
The scratches are more clear on the border and the flat surface more greyish with dirty.
Thanks for the feedback.
That's primarily a result of the cockpit materials, rather than texture resolution, which are still work-in-progress and not representative of the finished product. We are working on PBR materials and configuring the materials for best effect in the simulator.
