I have a problem with Unreal groom while binding asset  
the hair was made in xgen and imported following this video: [Hair at a Strand Level | Grooming your creations in Unreal Engine - YouTube](https://www.youtube.com/watch?v=__BScFPJy3E)

so this is how it is before I bind

and it seems to fade out along the length of hair strands.

Has this Groom been exported from Blender? If so, I found decreasing the B-spline resolution in the ‘Render’ tab of the hair system helps.

Any news or fixes for this issue? UE 5.5.3 and this is still a problem for grooms with alembic chache.
