Enemy AI FOV (Visual Display)

Hello everyone,

I had a question about what the best means of implementing an enemy FOV visually is. Currently in the game I am creating the enemies are running the Vector 3 angle function to determine if the player is in the field of view. Additionally, I have a ray cast being sent out from the enemy to the player in order to make sure objects are not obstructing the line of sight. This is all working properly, but I want to be able to display visually the enemy FOV to the player.

I am still in the mix of whether or not I want this game to be a top down, or over the shoulder 3rd person. With that being said, what have you all done in order to display an enemy FOV to the player and have it be accurate to the actual field of view from the script??

Thanks!!
