Alright I'm editing some of the "unusual" particles, just to mess around. I've finished one, have the file saved in the particles folder but I cannot get it to work. It says the particle doesn't exist. Couldn't find any particle tutorials so spare me. What do I do next? edit: here's some more info The particle ".pcf" file is called flies_fixed. The particle system in the file is called "superrare_flies_fixed". I have a particle system entity initiated in my map to spawn "superrare_flies_fixed" but I get the error message Attempting to create unknown particle system 'superrare_flies_fixed'
