Purple artifacts on lens flare in render

I was trying out settings for a high quality render (mostly taken from Unreal’s website) and got strange purple artifacts. The render took all night so I tested out some single frames and I believe it is from bloom and lens flare. Does anyone know why or if I can add these effects afterward? I added a frame for example

Hi there @hntercole

You’re running running out of RAM when testing this by chance, are you? I’ve saw some issues like that previously. Although, it definitely could be just from bloom/lens flare.

I don’ t believe so, I didn’t get any error codes and my task manager showed it stayed about 1gb under max.
