Hair Groom Rendering Problem (strands against distant background)

Hello

There are some tips and tricks to the referenced topic available at the forum (thanks!) but nothing really solved my problem:

Hair strands in front of objects far away are rendered in a weird way. In front of near objects, more close (but not in) to the focus, are rendered perfect.

The following settings I tried to solve the problem:

  • Activate “Cast Deep Shadow” at the light source

  • Activate “Cast Cinematic Shadow” at the hair groom

  • Anti-aliasing off → If somebody knows a solution to solve this issue I would be interested as well

And the following Console Variables:

r.MotionBlurQuality: 4
r.MotionBlurSeparable: 1
r.DepthOfFieldQuality: 4
r.BloomQuality: 5
r.Tonemapper.Quality: 5
r.RayTracing.GlobalIllumination: 1
r.RayTracing.GlobalIllumination.MaxBounces: 2
r.RayTracing.Reflections.MaxRoughness: 1
r.RayTracing.Reflections.MaxBounces: 2
r.RayTracing.Reflections.Shadows: 2
r.ScreenPercentage 200
r.TemporalAA.Upsampling 0
r.HairStrands.SkyLighting.IntegrationType: 1
r.HairStrands.SkyLighting.SampleCount: 32
r.HairStrands.Voxelization.Virtual.VoxelWorldSize: 0,15
r.HairStrands.Voxelization.Virtual.VoxelPageCountPerDim: 16
r.HairStrands.DOFDepth: 0
r.HairStrands.DeepShadow.SuperSampling: 1

Does anybody find a solution for this problem?

Thanks and best regards
