Player's hands and blood not affected by night vision

[Nash]

I think it's weird that Doomguy's hands aren't affected by the night vision goggles, as well as the blood sprites.

They both give off heat, after all...

Don't take such things too seriously. I won't change this behavior because there's nothing that makes the blood actor special and because I don't want this for the weapon.
