How To Enable The Periscope Scope Filters
TDW's Options File Editor Viewer needs to be installed.
See my tutorial Post #6 how to install it.

To enable the scope filters you need to go to the UI Tab in TDW's Options File Editor Viewer.
Change the Night Filters patch from false to true.
In the periscope station when you press the Hud button tick the enable at the top.
Click on the number showing opposite the colour you want to change.
Use the mouse wheel to change the number.
You will see the optic changing colour.
By using the 4 options you should be able to get a night vision that suites your vision.
