Only 3 emitter libraries are installed with Particle Illusion’s main installer: the “Sampler” library, the “Custom” library (which can be added to and edited), and the latest library from the current release – for instance “Emitters_2024.0”. All of the other libraries are in a separate installer which can be downloaded using the Help menu – Download Emitters… option. Note that after installing the Additional Emitter Libraries, Particle Illusion must be restarted.
