Top Down Mouse look with pitch

for now, I’d suggest simplifying it…

The reason it doesn’t work is that setting Set Actor Rotation twice, and the second node is superseding the first node. What I’d do to prove the concept, is to use:

  1. just the first Set Actor Rotation node.
  2. plug the whole rotation into it (not just the yaw)

Depending on how your player character is controlled, there might be an issue with Control rotation Vs Actor rotation. This isn’t an issue with your BP but with how your character is setup… if the problem persists after making the above changes, try using Set Control Rotation instead of Set Actor Rotation. I’m fairly sure that, if a pawn uses Control Rotation, it utterly ignores Actor (world) Rotation.

As you understand, in the long run, understanding how your pawns are controlled and setting them up optimally for your specific needs will really be helpful.
