Procedural Fire & Smoke

Hello All.

I have been experimenting for the past year with 3d noise on volumetric lights, using Cinema 4D. First appearing here:
And here:

I have developed it further to produce procedural fire and smoke.

These scenes contain only the torus and a single volumetric light with procedural 3d noise in the visbility channel. That's all. No particles or nuttin'.

In both of these, the camera is IN the flames at the end. True volumetric, fly-thru-able smoke and fire.

The 2 examples above are pretty much the same materials with only a few params tweaked.

I'm pretty happy with the results so far. Have you seen anything similar done in other 3d apps. I realize that smoke and fire are often best done in post, but this effect has the advantage that it is really "there", in the scene.
More to come...

Not bad, looking good so far. It needs a bit more work though. The fire in particular lacks depth. It feels as if there is a texture moving through the object. The smoke in the first example looks nice. Have you tried applying these materials to a particle system.

Good job.

Thanks. I think the fire will look a lot better once it's actually in a scene. This was just a proof of concept.
I have done some explorations of particel smoke as well:

Love the lil'chimny...

I don't know how this translates into C4D lingo, but in LW, one could create a good smoke effect (mind you I haven't actually tried this yet) by assigning the particles of a particle system as HyperVoxel Sprites, and projecting with additional cameras an image of either real smoke or some sort of procedural....

hope that helps in some way!
