custom groom animation

Hello!

I’m having an issue with a groom. I imported the groom from Maya using the MetaHuman for Maya plugin and created a Groom Binding to the skeletal mesh.

In the neutral/static pose everything looks correct. However, when the eyes move, part of the eyelashes drift a few millimeters away, while another part follows correctly.

In Maya, I modified the blendshapes (specifically around the eye area). Could this be the cause of the issue?
