Tutorial - Tornado

Here is the tutorial I used c: 

Emitter: create an emitter. Have them all in a sort of circle. 

That's what happens when you press play from there. 

Fields > Gravity
Open up the options and type in -30 in the Magnitude.

Makes the particles go up rather than all over the place. 

Fields > Vortex Options. 

Set it to 100000

 It's starting to look a bit more like a tornado now. The particles are actually spinning.

Select one of the particles.

Attributes > Particle shape, in the lifespan attributes, change lifespan mode to constant. And set a value of 2.6

In render attributes change it from Points to Multistreak. 

Do this for all the particles. 

Grab the outside ring of the particles and move it slightly along the x axis.

And this is what happens ^^

I don't think it looks too bad : D
