MetaHuman Hair Turns White at Distance (Not LOD, Not Fog)

Hi all,
I’m using UE5.5.4 for a cinematic project with a scaled MetaHuman (×3.4) and a custom strand-based groom (LOD 0 only). The hair material is:

  • Opaque
  • Using the Hair shading model
  • No fog, opacity, or distance fade
  • LOD 0 is forced, no LOD swaps
  • Material is clean (checked in graph)

Problem:

Hair looks great up close, but turns white/faded when the camera pulls away. It’s not fog (Apply Fogging is off), and not transparency — this is a fully opaque strand groom. It seems like a strand width / lighting issue at distance, maybe related to scaling.

Tried:

  • Reducing Hair Width / Root & Tip Scale
  • Turning off fog, SSAO, and volumetrics
  • Adjusting lighting and roughness
  • Forcing LOD 0
  • Testing in different maps

Still getting overbright, low-density hair that blends into the sky.

Has anyone hit this with scaled-up MetaHumans or strand grooms?
Any fix for preserving strand contrast and density from far away?

Thanks!
