Fov on 3 monitors
-
You can also increase pitch angles for triple monitor by editing 3dckpit.dat file for each of the planes. See this thread for details.
-
Unfortunately, BMS alters the vertical FOV whenever you change horizontal FOV.
It shouldn’t be done that way, but it is. You’re going to have a rough time trying to get a good horizontal FOV whilst still being able to read MFD’s clearly and without having to intentionally look down - unless you cut off some of your outside view by altering the .dat files to angle the default view downwards.

Vertical is in the pit files.
as the post docbrown mentions:
2. Open all the .dat files of the 3d pit planes you fly and increase the viewlimit_pitch_down value.
The file name is 3dckpit.dat
The cockpit folders are in:
C:\Falcon BMS 4.32\Data\Art\ckptartLike:
C:\Falcon BMS 4.32\Data\Art\ckptart\F-16C-50
C:\Falcon BMS 4.32\Data\Art\ckptart\F-16C-52You have to do this for all the folders or at least for all the models you wish to fly.
Now those are the day pit’s there are and the night pits… They are located under the folder:
C:\Falcon BMS 4.32\Data\Art\ckptartnonce again do the same for all of them.
Now you are ready Go Fly and Enjoy all of it’s Majesty and Glory.

Arty, he means that he wants the aspect ratio of the image to be different than the aspect ratio of the screen. Squares would show up as rectangles, circles become ovals, etc. I think that is possible if you just specify a non-native resolution of the output frame and display it on your monitor. For example displaying a 1600x1000px image on a 1600x900 pixel monitor. You’d get more vertical information at any given horizontal FOV at the expense of distortion.
I run 3x 1920x1080 monitors in a 16:3 aspect ratio. It really really helps to have TrackIR and a FOV control at your fingertips (Warthog MIC switch fore-aft). I have no problem with the “bunker slit” view on the world I have for MFDs or anything else.

What I mean is that as you increase the horizontal FOV, what you can see vertically is diminished.
For example, if BMS was a standard piece of paper, your horizontal “FOV” is the 8.5", and the vertical “FOV” is 11". Adding a piece of paper on either side, the horizontal “FOV” has increased to 25.5", but in BMS, the vertical will have shrunk to less than 11".
It doesn’t have to be done that way, but it is. The consequence is users who either prefer higher FOV, or require higher FOV, get the short end of the stick with regards to vertical FOV.

Be careful with your language there. “When you increase the horizontal FOV.” No. Different monitors don’t change the hFOV setting. Different monitors change the aspect ratio. If your new monitor has a larger aspect ratio at a fixed hFOV setting then your vFOV displayed is smaller. That’s just a simple mathematical consequence. If you add to the width to your display and want the same vFOV, just increase hFOV until it compensates for the changes aspect ratio. I have no sympathy for the user that adds to their display and gets the false impression that something was taken away. The adjustment is easily made.

This is why I fly with a pair of TFT monitors with my MFDs on them. Makes all the difference in the world.

Hi guys!
Can somebody explain to me why is the picture distorted ONLY in the side monitors and not in the central, especially on high valued FOVs (eg 130 or 140 degrees)?
Please see in the following example how the size of the HUD changes as it passes to the side monitors, by rotating my head tracker! In the center monitor, the HUD (and everything else looks OK:
I do not accept the “mismatch in aspect ratio” as a reason, because I guess it would have affected the geometry of the projected objects at the central monitor too, right?

I believe it’s distortion from the way Falcon gfx engine displays FOV. The more to the edge the more the distortion. Everything inside the default fov area is just not distorted.
I believe this was discussed already in another thread.Sent from TapaTalk

That’s a normal distortion for rectilinear projection 3D to 2D mapping. http://www.tawbaware.com/projections.htm

Thanks guys!
Also found this video which explains a lot of things…
