Hi team,
I have noticed that on the SU-25 it is possible to bind a key to lower the HUD glass. However, once down I can find now way to raise the HUD glass again. The binding for moving the glass back up doesn't function. Either I am doing something wrong or it's a bug.
Not related but the HUD reflection with the sun behind you is possibly realistic, but overwhelmingly opaque, regarding ease of use.
