Locking the render scale in the new upload at 100% fixed the hypnosis rendering! Thank you so much!
The head turn to look at a noise is also a cool addition and the new audio is great. I have one suggestion and one bug to report.
Fen is often looking the wrong way for the body glow hypnosis to lead to eye hypnosis. I would suggest that it look around to detect body-hypnotised players or for affected players to make a noise like a whimper which then gets Fen's attention.
I've noticed that "Spawn player prey" spawns a non-player prey if pressed while in MonsterPOV (or at least it stays in the POV). The menu changes as if the player is in a body (showing Prey Debug and Enter spectator mode) but the camera doesn't.
