Dot Lock Target  

This mod will remove the fx ring around both target lock AND zoom-in function, it is because in the game they share the same asset and you cannot have one without the other.

FAQ:

Q: Can you make it disappear completely?
A: no, through tests I found that the target lock dot is explicitly used in a lot of different assets and even some of the UI elements, removing breaks multiple assets in the game.

Q: Can you change it's color ? 
A: As of right now I'm still looking for the parameter or material that controls its color as this is originally a black-and-white mask so changing the texture itself again will break other elements of the game, so look out for that in a future update
