I've tried a few methods to get this file to work, but I figured it would be easier to come here and ask starting from scratch. I have created a custom particle file called "core_kaboom.pcf" within TF2's particle editor, using only tf2/hl2 materials. I have saved the file in tf/particles so i can open and view it whenever I need to. In hammer, I created an info_particle_system entity that will be triggered by a button (for now just to test). The inputs and outputs work correctly, but the particle effects do not show. I've tried putting the pcf file in a few places to see if it would work, but it kept returning errors such as "Attempting to precache unknown particle system" and "Attempting to create unknown particle system" So, where do I put the .pcf and what other files must I edit to make it work?
