I'm really struggling here so explain it to me like I'm five.
This is for 3D btw!
Basically the player rotates around a central point and I need to get the instance of a node that is both a) the closest one and b) currently visible (ie: if one is closer but behind the player, it doesn't count)
I think I can figure out the closest one but I haven't the foggiest on how to tell if something is currently visible from a specific camera. Is anything like this possible?
