If you want to use fire in 3D scene, you can use this 3D fire which won’t affect your system performance and rendering. To animate the fire ring size, just scale or animate the size of BezierCircle in the blender file. For the fire texture, I have used a transparent fire video. If you don’t know how to use the texture, go to shader editor, and locate the video file from texture NODE and press Enter.
