Basically the main trunks are emitted with state 0.
The branches spawn from 'state 0' particles at every nth frame and they are 'state1'.
Then the same happens again for the smaller branches.
They are 'state 2', and spawn off of 'state 1'
I posted some more info (so I could post the tree etc.) in this thread on the forum
Looks nice. :)
