These are descriptions of the attributes in
the hairConstraintShape node. For more information, see
Set up hair constraints.
- Constraint Method
-
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.
- Stiffness
-
This
is the stiffness of the spring attachments created by the constraint.
The higher the Stiffness value, the more the
curves tend toward the position of the rest curves. Default rest curves
are normal to the object’s surface.
- Glue Strength
-
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.
- Nearest
-
This is the point along
the hair curve nearest to the constraint locator at the start frame.
- U Parameter
-
Using the value defined
in the U Parameter attribute, constrains
the point at that U value along the curve. The end of the curve
is 1.0.
- U Distance
-
Using the value defined
in the U Distance attribute, constrains
the point at that distance in worldspace from the start of the curve.
- U Parameter
-
If
the Point Method is U
Parameter, this is the U value used in determining the
point to constrain to along the curve. A value of 1 represents the tip
of the hair curve.
- U Distance
-
If
the Point Method is U
Distance, this is the U distance value, in world space
units, used in determining the point to constrain to along the curve.
- Curve Indices
-
These
are the IDs of the hair curves affected by the constraint. The ID
represents the index of the hair (UV grid location) on the hair
system.
WarningCurve
Indices IDs should not be edited.
