bottom line: as Andy has suggested and Epervier has seemingly confirmed, if you play around with values in the hier.him, you end with a lowered gunner, but with a marked gap between the wings and the fuselage where you can see through, when you look out of the left window and zoom out;
granted, I dont to that very often, in fact I have not flown the 540 before, I only shot at it so I did not notice any weird stuff in its cockpit;
so while you gain a better view over the nose with the smaller gunner, you get a rather weird looking gap in the left wingroot, where you can see through and backwards in the game;
depends on what you prefer now;
values to change are these:
[Root]
Mesh Root
Parent _ROOT_
Attaching 1 0 0 0 1 0 0 0 1 0.75 -0.1 -0.75
change the 0.75 -0.1 -0.75 to whatever you like between 0.55 -0.1 -0.55 and 1.12 -0.1 -1.12) the last three values are the original ones as in the original hier.him
0.75 gives the best compromise in my opinion between height of front gunner turret and wingroot gap in standard view - zoomed out the gap only grows
as said, just as you prefer....
on a sidenote, is there a way to get the Goertz bombsight and bombardier view from the Potez 540 into the Amiot 143?
the French used the Goertz extensively in their bombers and it was even preferred to the Norden as it was easier to operate and of all things more accurate than the Norden when employed by the rather low flying slow early war Allied bombers according to some sources...
