Hello, I am having a problem with displaying trails outside the PIE mode for my game. For some reason it works as intended while I’m in the editor, for all my 4 players. But once I build it doesn’t show anymore for any of the 4 players. I tried to make the trails show in a different way now, as I initially just had it attached to a player. Now I’m spawning it on event and nothing - only in editor 100% perfect. Each player spawns 1 of 2 types of ribbon particle emitters, so a total of 8 are displayed when playing. Works and looks perfect… until I try it in build. Any tips on this? Thank you! Virgil ---

FYI, I’m seeing this behavior too. This is apparently a recent regression in the 4.11 branch, happening between 3/21/16 and 3/23/16. I suspect the offending changelist is here: [https://github.com/EpicGames/UnrealEngine/commit/3eaef9cd399f81a2b03cbc488c02cc043de82a15](https://github.com/EpicGames/UnrealEngine/commit/3eaef9cd399f81a2b03cbc488c02cc043de82a15) ---

So, no solution to this bug if we’re up on 4.11? I did manage to make it happen in play mode, out of desperation 😃 But it’s a very bad way to have it. What I did was I have spawned the same trail about 5 times and it shows up … which is not a performance friendly fix unfortunately. ---

FYI, I confirmed that backing out the above changelist from 4.11 fixed the issue for us. I’m not sure what other side-effects that might have, however. ---

HI Virgil, This was reported with UE-29241 and looks to have been resolved internally already. Thank you! Tim ---

Go into the particle system itself. Click on the empty space and change your bounds to what you need. Then along the tool bar is ‘Bounds’ Hover over the drop down arrow and click ‘Set fixed Bounds’ I’ve had an issue where a particle effect won’t render. And This fixed my issue. Hope it helps yours. ---
