How do you use this thing? It only seems to generate tiny purple dots when I try…

Same here. No idea how it works. @ Did you get it working?

Appears to be a serious memory leak in Niagara. I created a basic system with particles that should only live for 3 seconds. When added to the scene, I notice the FPS slowly go down from 120 to 5 over a few minutes and task manager just UE4 ever increasing memory consumption.

There’s a memory leak in previous versions of the nVidia driver. If you are using an nVidia card, make sure you update drivers to latest.

Yep, already running the latest nvidia GeForce drivers, so guess that rules that out. Leak only occurs while a Niagara system is in the level. Delete it from the level and the leaking stops.

Yes, I got the same package error ETS2:
UATHelper: Packaging (Android (ETC2)): LogInit: Display: LogObj: Error: LoadConfig (/Script/Engine.Default__RendererSettings): import failed for bEnableAlphaChannelInPostProcessing in: False
And actually, I don’t want to switch to the 4.20 version. And I’ll wait for it to work more stable.
