Rotation, different behavior between Yaw, and pitch/roll

Hi,
I’m currently trying to learn my way through UE4, one of my first step being working on the camera control. More specificly making it rotate with the mouse when I hold right mouse button.
I pretty much ended up with this blueprint ( after looking at Devin Sherry’s video about camera control ) for my character actor :

Now my problem is this, this blue print work perfectly for Pitch ( though I did had to put a -90 & 90° limitation for this one ) and roll. But it has no effect when I try it on Yaw ( neither on the statick mesh, or springarm/camera ). What can be the reason ? I’m guessing it comes from something in Components/characterMovement, but I couldn’t find anything ‘playing’ with the value in it .
Any idea ? Thank you.

Hey, I didn’t try to reproduce your error, but I think it has to do with having the “Use Controller Rotation Yaw” check box (in your actor BP) ticked.

Hope unticking the check box fixes it! Good luck.
