Disable mouse free look


this got me a bit unprepared.

So, i have a PlayerCharacter which has “Use Controller Rotation Yaw” set to true. I got a PlayerController that shows the mouse cursor and has some controls for WASD movement.
Now, if i press any mouse button, the character rotates automatically with the mouse, which is exactly what i dont want!

I already tried to ignore look input (then no AddControllerYawInput node works anymore, which i need for AD rotation), i tried to disable the mouse cursor (no effect) and played around with the UseControllerRotationYaw bool (which has the same effect as the ignorelookinput).

Is there any way to disable this behaviour AND still being able to use AddControllerYawInput ?

Thanks in advance!
