These are descriptions of the attributes in the hairConstraintShape node. For more information, see Set up hair constraints.
This is the type of constraint: Rubber Band, Stick, Transform, Hair To Hair, Hair Bunch, Collide Sphere, Collide Cube. For descriptions of these constraint types, see Hair constraint types.
This is the strength of the glue holding the constraint. A value less than one can allow the constraint to break during the simulation if the tension exceeds the strength. A value of one is infinitely strong and will not break. Rewind to frame 1 in order to re-glue. After a break, a setting of 1 reattaches the glue.
Point Method
These are the methods for calculating what point along the hair curve the constraint uses.
