So I'm hoping someone can help with this.

I am trying to make a custom particle system for Portal 2 by using the Alien Swarm Particle Editor. I have created the particle system and am happy with it, and imported it to Portal 2 (as well as the necessary material files), as well as adding the new system to the particle manifest.

The system shows up in the particle browser in hammer, but when compiling a map (fullbright or not) the system does not show up. I have tried:

Having the system start active
Having the system start inactive and be triggered by a logic_auto or the developer console (ent_fire)
Having no control points
Using an info_target as a control point

I can't seem to figure why this system isn't showing in game. Any ideas?

Thanks a ton,

Have you tried putting an exclamation before the particle's path in the particle manifest? Doing this makes it so it precaches it on-map-spawn, I believe.
An example from my own particle manifest:
"file" "!particles/portalgun.pcf"

Also, I think you can test out particles ingame using a console command, but I can't remember it. Try typing "particle" into the console and see what comes up.

The ! does not appear to help, thanks for trying though! Does anyone else have ideas of what to do for this?

What sort of spawner do you have? Spawn_once (I think that's the name, I haven't used the particle editor in ages) effects loop in the particle browser and editor, but not in the game--they show only once and disappear.

Hey,

I'm using the spawn_continuously spawner. The particles don't even show once and then loop however.

Shot in the dark, have you watched THW's Particle System tutorial? He may mention something there that you might've missed.

Fixed by adding the particle to the vpk in my dlc3 folder, where the particle was originally.
