Until this group consensus fest convinces Hitech to change the game for you.
I forgot about something I had started working on during the alpha because I didn't like the new gunsight alpha mask. You can put sunglasses on your gunsight reflector plate. Night or day it shifts the picture through the gunsight to a more monochrome improving the contrast of the con to its surroundings. Not it's clarity or color. Sunglasses in the real world do the same thing with blue, green, or orange. In AH3 red or orange works best. I discovered this trying to lighten up Waffle's dark grey mask on the gunsight reflector plates. I used to be able to do it in AH2. Instead I discovered that red and amber acted a lot like amber shooting glasses.
At first it's disconcerting until you notice things like looking at a con from above over trees it stands out better. Or diving on a town in our short darkness, the lines of the buildings stand out better as a contrast in the monochrome. It even holds back a bit longer the sun whiteout effect.
I gave up trying to get Hitech to do things in consensus fests like this and started looking at the tools he provides to make minor adjustments to the game for solutions. From watching Hitech for 14 years, you gents may have better luck asking him to allow toggling off the three parts of the icon. Range counter, country tag, and aircraft type since he gives you the ability to completely turn off the icon.
Night time, Amber Mask with red dot. 512x512 8bit bitmap. Mask R22 G9 B0. Darkens clutter and makes objects stand out.
Dob's screen capture under low light conditions, doesn't look like full night. Dark gray gunsight mask in effect and it makes objects as you look through it look like objects in full dark under low light conditions.
