Have other users found this dependable? I can't file a bug because it's not consistent but I'm finding in both the editor and my builds I'd say about a 1/15 of the time particles fail to play. I have some projectiles that have trails and looping effects are enabled with a simple SetActive on the PP effect gameobject and yet nothing displays. If this is the editor and I pause and go click on the object this seems to goose PP and suddenly the FX kicks on so I can't tell what state anything is in. I do not have visibility pausing on. I've never seen this problem with any non PP particles. I have to admit this is really vague and hard to track down especially as its within a huge project but I can't seem to find a good place to start diagnosing the problem. My best guess is maybe connected to when PP creates Unity particle system effects? Is there any way to get it to minimize the time it modifies those systems? Does it ever destroy them and can that be prevented?
