In that scene, Rey seems to be running quite a long distance before she reaches the ship whereas the ship is right next to the castle. Perhaps a different model could be used or the ship could be rotated/reversed/recoloured?
Well the point is to use the ship that Finn was boarding so it is implied that Rey will go with him (Yes, she probably would have no idea which one it was, but maybe she knows ship types, the Force told her, or at worst she’s just getting on the first ship she sees, whatever). I figure that she took a more scenic route as well, since she’s viewing it through the trees. Finn probably just used the path.
My original thought with this was to have her approach the front, but I have been able to find exactly zero usable reference material for the Meson Martinet. It might be for the better though, since it’s pretty unmistakable which ship it is.
