TimRobertsen's post in Permanently repositioning the FLOLS overlay? was marked as the answer
Please forgive me!
After some testing I found me suspicion to be correct.
"local x" and "local y" are the coordinates for the overlay.
Marked with red circle in the image.
The coordinates are from right to left, and bottom to top.
"1" is minimum value (screen edge), "2" is center of screen ... I didn't test max value.
FLOLS.lua location: DCS World\Mods\tech\Supercarrier\PLATCameraUI
I used Notepad++ to edit FLOLS.lua.
I hope this helps someone 🙂
Much love, stay safe!
