go to Preferences >>> Firestorm >>> Avatar and set the two sliders at the top to limit horizontal and vertical movement of your av's head to zero
First let me start by saying I know this is an old thread, but I came across it while trying to solve this issue myself. This creates a dilema:
1) Bump an old thread and be called for it.
2) Create a new thread and be called out for not using search (even if you did) and using one of the old threads.
It's usually a no-win situation and you get called out which ever way you try (sometimes even getting called out for both).
So, I apologize in advance.
Anyways, Like I was saying I too was trying to solve the issue of my character's head constantly following the mouse.
Setting the yaw and pitch to 0 in the advanced settings seems to have solved the issue slightly, but not completely.
My character no longer follows my mouse all over the place, but seems to still turn her head based on camera rotation. This is not normally an issue, but is really annoying when trying to click something on her face, like her eyes.
It feels like I'm trying to feed a two year old that keeps shaking their head no as I try to turn the camera to get a good view of her face so I can edit her eyes.
Note: Making airplane or choo choo noises doesn't help either!
The "Stop Animating Me" option also doesn't seem like a solution (unless it's not working as intended) since the character only stops being animated for a spit second and resumes moving again shortly after the option is pressed or the camera is moved.
