I developed a "fake" volumetric fire simulation in Unity. In short, I use a set of alpha-clipped and blended cards stacked in front of each other, and the fire fades in/out based on the distance from the center card.
I made a brief video covering how it works: https://youtu.be/AcCGoEsmUz8
You can download the .unitypackage for free to re-use or extend it for your own projects: Enflame - Unity Game Asset | OccaSoftware
Let me know what you think. Is there anything that can be done better?
I'd love to extend it to render using real volumetrics, but I haven't yet figured out how to create a convincing flame shape or how to light it. Anyone know of any resources?
