It is a simple one-piece sculpted cylinder object, made in Blender for fun, can be used anywhere in multiple copies, not affecting the processing power needed. See preview image No04, where it is used in an AR app in Unity, with particle objects to resemble fire. Suitable for any VR-AR app due to its simplicity and low-poly, ready for the texture of your choice. Low-cost object, use it as you wish, i will be very glad to see it in your scenes/apps or wherever you wish!
