I am working on a old cmivfx tutorial called network relationships vol.1

In this tutorial we create and animate a tornado out of points. Using the volume to attribute node i can see it in the view port but I am unable to get it to work with the smoke solver.

Could some one show me an example of the work flow for using points to control smoke or pyro sims.
Or if theirs a link to a good tutorial i can be pointed to that would be great.

I have seen the digital tutors CREATE FIRE & SMOKE SIMULATIONS
with custom Pyro FX


Here is the Houdini file of the Tornado i was working with.

There is a nice example Tornado on this links page [forums.odforce.net]. As well as other examples. Check out Diego's Vortex Cloud as well for a cloud like spiral effect.
