I have downloaded the emitter libraries but cannot find any folder or even by creating one, and placing them 'unzipped' into the Particle Illusion SE folder(s), that will let the Particle Illusion SE DEMO version, find them....... How do you make the software locate new libraries ? Or will they NOT function with the demo version of SE ?
They don't show up automatically -- only the current library is shown. To load another one, r-click (ctrl-click on a 1-button Mac) in the library window and "load library", then browse to the folder where you put them, and select the one you want.
particleIllusion 3.0 is a little better in that you can use a "quickload" menu, or use the library manager.
