This is a way to get the unused animation for first person pounce besides modding the animation to be in the game.F.Y.I this animation is the game.So people could make this mod possible!
Step 1: Get a survivor in a doorway or in between 2 walls. Step 2: As Hunter, Pounce the survivor. Step 3: Place a prop (Preferably a fence) in the way, just as I did. Step 4: You Have yourself a firsperson hunter! You might need the barricade mod to this or if you are skilled you could do it without the barricade mod just by going to a place with a barricade.
