Extream glow effect on MetaHuman Hair using tight DOF

Hi everyone,

I’m encountering a visual artifact issue with MetaHuman hair when using a tight depth of field. Specifically, I notice a glow or halo effect around the edges of the hair (mostly the beard), which becomes quite pronounced and distracting.

Details:
Engine Version: Unreal Engine 5.3
MetaHuman Version: 2.03 Highest Qualtiy download setting.

Issue Description:
When applying a tight depth of field to my scene, the edges of the MetaHuman’s hair display a glow or halo effect. This artifact is particularly visible around finer hair strands and is affecting the visual quality of my renders.

Steps to Reproduce:

  1. Place a MetaHuman in a scene.
  2. Apply a tight depth of field using the camera settings:
  3. Observe the hair edges, especially around the finer strands.

What I’ve Tried:
Adjusting depth of field settings - Less DOF dose reduce the effect. However I do like the shallower DOF look for artistic reasions.
Changing anti-aliasing settings - I tried to also follow this tutorial by William Faucher. I would apply a concle command called r.TemporalAA.Upsampling and setting it to 0 (off). Unfortunaly this did not work for me.

Solution at time 2:55

My focus plane is position at the face.

Has anyone else encountered this issue or does anyone have suggestions for resolving this visual artifact? Any help or guidance would be greatly appreciated!

Thanks in advance!
