Channel: peter quint
Date: 31/01/2016

This tutorial is from 2012 and was made for Houdini 11. 

It was originally part of the PQHoudini channel on vimeo.

While Houdini has changed a great deal over the past years some aspects of this tutorial are still relevant.

*NOTE THE METHOD OF SOURCING SMOKE HAS CHANGED IN HOUDINI 12 SO YOU CAN NO LONGER FOLLOW THIS VIDEO EXACTLY*
This video takes you through the scene file used to create the effect of dry ice flowing down over some letters. It uses the advanced characteristics of the apply_source node to create bespoke sources and sinks for the gas, and uses the gas dissipate microsolver to make the gas evaporate as it warms up. The scene file is at sites.google.com/site/pqhoudinitutorial/.
It is worth watching the Sourcing and Smoke series of videos and, if you are starting from scratch, the Volumes series before this video.
