Here’s a neat trick in order to spawn particles from particles. The key element is to start the emission from the spawned particles when the main particles reach their end of lifetime. The formula I use in the video in order to quickly type a row of consecutive numbers is “num*1″. This little formula takes all the selected elements and starts with 0 and counts up to the sum of the selected elements minus 1. In this quick tip I used it to number through the segments instead of typing them manually.
For anyone interested in other useful formulas just take a look in this thread of mine on (no audio)
