How to make jet engine fire using niagara?

Thank you for your idea, I found I have my UltraDynamicSky assets and almost made my cylinder material. But I have couple of problems left.

  1. I couldn’t find the static mesh editor. The internet says that the static mesh editor is gone in UE5, but the modeling mode is left. Am I doing right? Using static mesh for the cylinder, using modeling mode in the level blueprint to take off the cylinder ends and save it as a new mesh?
  2. Since I don’t have the cylinder mesh yet, I still don’t get how to grow and shrink its length. As I press the accelerate button by keyboard or gamepad, the fire material has to grow its length from nothing, instead of appearing all of a sudden(as I release the button, the fire should shrink slowly).
    Is there any way to manage the length of the material(or cylinder) using parameters?
    Or handling the amount of material exposure?

    Sorry for rough drawing, but this is what I want to talk about handling material exposure
    It’s like leaving the cylinder stay still and only moving the texture back and forth
