Halo Artifact Around Character in Path Tracing Render

Hi everyone,

I’m encountering a strange halo artifact around my character when rendering using Path Tracing with Lumen. This halo is not visible when playing the sequence directly in the editor viewport.

This screenshot shows the halo artifact in the rendered output. It appears that the background isn’t blurring correctly around the character in the render.

I’m wondering if this might be a specific interaction between Lumen and Path Tracing during rendering, or perhaps a sequencer rendering setting I’m overlooking.

Any insights or suggestions on how to eliminate this halo artifact would be greatly appreciated.

I am using:
Unreal Engine 5.4
NVIDIA RTX 3080

Thanks in advance!

There is a bug in 5.5 that presents this way. Can you disable Alpha Output in the project prefs and see if it goes away? Its since been fixed but I have lost track if its out in a hotfix yet.
