Volumetric fractal smoke - 2 approaches

Two little experiments to create pseudo-volumetric smoke objects in After Effects, one using Particular, the other using the built-in fractal noise plugin in AE and an awful lot of layers.

Both have their own unique look. The Fractal noise version took hours to render compared to the Particular version (which took about 30 mins). The project files are free to download and reuse under a Creative Commons license from the Digital Distortion website.

Particular version:

Fractal noise version:

There are issues with visual artifacts when you get closer in to the fractal noise version (you can see the individual layers, creating an ugly "scanline" effect), so hopefully someone else out there can improve the technique and share it!

Update: Based on feedback, I've done a new version of the Particular one, using a custom smoke comp generated using fractal noise. This gives kind of a hybrid look of the two approaches.

The project file is downloadable here.

Volumetric Smoke with Trapcode Particular

This was an attempt at creating a volumetric looking smoke effect. It was totally improvised so it shows how I experiment to get the settings right.

After rendering the final clip I noticed I had to change the Particle>Size over Life curve so the particles size faded out rather than just disappearing abruptly. I also setup Aux>Opacity over Life so the auxiliary particles faded out (using opacity). Tutorial:
