The other reason why i don't want to use actual volumetrics for the smoke, is because volmetrics need a direct source of light to look good, and in this case the smoke will be mostly in shadows, so it doesn't look well, aside from looking very plain if i use emmisive volume.
I will try fixing it by making the smoke particles get smaller to nothing over time, to see if it looks less unnatural. Ideally it would be best to make them FADE, but the method doesn't work in EEVEE.
