Here's a look at the basics of smoke simulations. It is worth looking at the video series on volumes before doing the smoke tutorials.
This first part looks at setting up a simulation, the fields involved, how to visualise them. It also looks at temperature and bouyancy as well as vortex confinement.
In this video tutorial we'll have a look at some smoke techniques. This uses a smoke example to examine source variations and upres (techniques which are useful preparation for the pyrofx tools).
In this first part we look at using a noise based source, and at rest fields. We then introduce the upres technique of adding detail.
