I saw your movie and your flying paints and i can't figure out how you can have white HUD. I know its ''H'' or Ctrl+H to change the colour but i dont have a white one

Open your ...\Ubisoft\Eagle Dynamics\Lock On\Config\View\View.lua

Search for: HUD RGB color

Then change the 256 color palette for the aircraft of choice to: {255, 255, 255}

Save the View.lua file and you're done!
