What function does Skyrim use to limit the third person perspective zoom-in after the player is transformed into a werewolf?

[TheSilverSmith]

I'm trying to use the Playable Monster Mod, but for some reason when I go into first person, the game crashes. I suspect this is because first person isn't supported for creature races. It's easy enough to just stay in third person, but I want to add a function to a script somewhere to limit the perspective to first person. I want to be sure that my game won't just crash on me if I ever accidentally press the F key when transformed. Does anyone know what function Skyrim calls to limit the third person zoom-in when the player is a werewolf?
