When I tried to simulate the animated mesh in nHair and create Ornatrix hair from Alembic cached curve, after turning on the HairFromGuidesNode option, the hair seems to be over-rotated compared to the Alembic cached curve.

This happened when the “Set Rotation” is not selected in GroundStrandsNode, and if I turn off the “Set Position”, the shape remains but the position is off.

I also tried to remove the OxHairSystem mesh animation (guessing that this error might be related to the OxHairSystem mesh animation) and deselected “Set Rotation and “Set Position” in GroundStrandsNode option. However, there are still various errors occurred no matter what options I selected in the HairFromGuidesNode function.

Is there any solution for this issue?

I’ve attached the scene file and alembic cache file here for reference.
