I have an arm(Static Mesh) attached to the player character. The player can use the mouse to rotate it. The arm starts from the elbow where the origin is. The mouse input values X and Y are used in an “Add local rotation” node. The arm moves up and down, left and right.
I also want to roll the arm. Rolling the arm also rolls the origin. For example, if I roll it 90 degrees then moving the mouse up and down actually moves the arm from left to right.
How do I move the arm up/down/left/right regardless of roll?
So I added a new static mesh component as a parent of my arm. The parent should not rotate at all. The arm can roll with an “add local rotation” node and it should rotate left/right/up/down based on the origin of the parent using an “add relative rotation” node. That makes sense to me.
However this still does not happen. Not sure what I’m getting wrong.
X (Roll) is the left-right movement
Y (Pitch) is the up-down movement
Z (Yaw) is the tilting movement
It is a bit reversed but I assume it’s this way because of my mouse action values (X and Y).
In the first part, the arm moves normally. As soon as I tilt the arm it starts going sideways. You can see which way the arm should be moving by looking at the camera’s movement. If the camera moves up, the arm should also move up, and so on.

And actually I’m a noob noob on learning .
I’m pretty sure someone in the community would help you, they vary skilled, and like to help people.
