Notice how the tail light sprite is continuously rotating even if the angle between it and the camera isn’t changing and in both directions.

  
I’ve achieved similar effect but it only rotates if the angle between the sprite and the camera changes. I am using a plane with a simple sprite WPO.

You could just have the plane (transform into a cone to fit the tail light, but still with a square UV) and just use a Panner to move the texture.

Not sure I understand how it would achieve the desired effect.

Solved by using angle between vectors with component basis vector X and constant 3 vector 0,1,0. Then piping that in rotator.
