Irrlicht Engine

I am modifying the camera class so that it will simulate the player walking, it will jerk up and down and side to side and stuff. I tried moving the actual node of the camera, but with the collider animator it jerks to weird because it pulls the camera back to the ground... is there a way to change the camera's position without changing the nodes position?

You can simulate a change of the position by changing the Frustrum, but this is mostly used for zoom
