I have tried to ask the same question on the main MSFS forum but looks like it
is too specific, maybe here I can get some clues. I’m trying to simulate a
helmet-mounted display for my [jetpack
project](https://forums.flightsimulator.com/t/announce-your-personal-jetpack-
jw1/417954) (it’s like a HUD glass but always in front of the cockpit camera).
I have partial success - by using simvars CAMERA GAMEPLAY PITCH YAW:0 and
CAMERA GAMEPLAY PITCH YAW:1 I am able to rotate dynamic texture quite
smoothly, but with mouse movements only. When I use a head tracker or VR, this
variable does not react to head pitch/yaw changes. It doesn’t seem to be a bug
- during VR mode the mouse still works, so what I really miss - another
variable specifically for tracking device rotation values. Are there any? Or
tracking angles can be added to the CAMERA GAMEPLAY PITCH YAW value - not
perfect but fair solution. Years ago I worked as a dev on a helicopter sim,
where we had an actual node in the cockpit following the camera, so it was
possible to add a child element to it and then the child always rotated/moved
together with the camera, but that will not work in MSFS as I can see. Maybe
alternative methods of rendering exist that can do the same job - draw dynamic
data on the screen in a fixed position. Any suggestions are welcome.
