How to create a flame effect for moving lighter in first person view

Hi everyone, I’ve been trying to create a flame effect for a lighter like this:

I chose this as my reference because I want the flame to react to the movement of the player.
Me and my friend try to create the effect by using a particle system with a ellipse shape sprite and make it scale smaller according to the life. This is our current progress: https://media.giphy.com/media/lYhn4HbBCIZrQ63W0z/giphy.gif

It is definitely different from the given reference as we take another approach to this.
I tried to search in the forum and these are what I have found so far:

  1. Candle Fire - Rendering - Epic Developer Community Forums

  2. How to create a zippo lighter flame effect? - Rendering - Epic Developer Community Forums

But i don’t know how to follow the steps to create them and are there examples or ideas to do it?
