Hair on a spline with surface deformer


Hi there,
I have a hair object on a spline with a surface deformer to create the character’s eyelashes.
The problem arises when closing the eyelids, the hair guides rotate and the hairs form waves.
Does anyone know how I can keep the orientation of the guides to avoid that?


In case something similar happens to someone, the solution I have found is to make a spline for the upper eyelid and another for the lower one instead of just one for both eyelids. Guides keep their orientation.
