This package contains 13 models of smoke and steam.

The models are made of particles which are swirling around, rising through natural convection currents. The models represent a series. The initial stage is Smoke Model #1 in this package, and culminates with Smoke Model #26 in the second package.

The models can be used for anything emitting smoke or steam, including the ofuro (or "hot tub").

Sometimes, you want to add smoke or steam to a scene by painting the scene after it is composed. But you need a model for the way that the light and shadow of your scene fall on the smoke. These can give you a good representative start, even if you do ultimately use post-processing for the majority of your scene.
