I make that shield and apply Ping360 color scheme. That improve visiblity at least twice. Can’t test it in same place as previous video yet, but i do some tests in “open sea”. In that case i have only one target, but i can feel the difference.

I can’t use that code, something broken here. But i butch it apart, make something working and calculate the color coefficient table.
