I have been trying to play around with Blender’s new smoke sim lately and have known that generating fire via some tweaks is possible, though it might seem a bit like a cheat, it still works.
Anyway, here’s what I have achieved so far. And am very happy with the results.

It looks really nice man. But i guess the flames have a too sharp/spiky structure in comparison to real flames. This is coming from someone who has not clue about the topic though, it’s just my first thought. Stil looking awesome!
Hmm, the transition from fire to smoke is a little odd. The dissolve time is really 20? The smoke stays queit a while…
hmm thats really cool - more like a fireball than normal fire… it actually looks good… maybe you can show it off in a scene?
Hmmmm, yeah. I think I overcompressed the color ramps. Thanks, man.
Hi, Raub. Yeah, it is 20. I was surprised with the longetivity too. It might be some setting that was partnered with the dissolve. I’m not sure. :o
By the way, I was really really inspired by your tutorial. Thanks so much for sharing.

Really nice what res domain did you use? That bright emitter does a nice job of obscuring the lumpy emission point.
Thanks, David. I used 112 for the Domain Res.
