Hi,

I made a ribbon particle emitter that is spawned with “Spawn Emitter Attached” to a movable physics vehicles root joint. It works great in editor but on IOS devices the track show up about 1/10 times. So the emitter is rendering and “working” just not showing up every time. Is my ribbon particle too expensive or similar?

Thanks!

Hi Tireless,

This was previously reported with UE-29241 and has already been fixed for 4.12. You can test this out with the latest Preview 5 release for 4.12 available in the Launcher now.

Thank you!

Tim
