apply scale/rotation/... and Curve modifier
Just because i'm used to work that way, I like to reset my scale and rotation when working.
I did this with the hair mesh and hair curve (before applying the modifier), but it acts weird; it does not match.
I need to give the mesh X -90° & Z -90°.
Do you understand why ? If they have the same scale, origin and rotation; why don't they match ?
