A video would be amazing while we wait
There is two other issues in regards to scopes that you might take a peek at since your in the mix.
Sorry,I don't know who but a modder fixed the scopes not fully lowering into the enclosure but did not touch the blackout texture.When you raise the scope slightly it shows its out of its enclosure when your standing on the conning deck but in scope view the view is still blacked out.I Searched for hours to find this texture but I could not.
Second is when in interior command room and I press key to raise periscope fully I see the scope rise up but when I enter the scope view its still lowered fully.
