no ones replying to my messages about this so im goin to post this up and hopefully someone could get this to work

first off we would need a black and white vision..that would probably be the easiest

second we would need to make players i know there is a code for this but only the host can see would need to make a script to highlight players based off that code or however you do it so that everyone can see highlighted players

combine those 2 things together and bingo you have thermal vision!!
