To constrain the curtain in the tied-back position
1 Click the
button on the Status Line to display the Start curves (not
the CVs).
2 With the bound hair curves still selected, select Hair > Create Constraint
> Hair to Hair.
A constraint locator is created and connected to the selected curves.
3 In the hairConstraintShape tab in the Attribute Editor, set the constraint
attributes as follows:
Stiffness to 0.5 (default)
Glue Strength to 1.0 (default)
Point Method to Nearest (default) (Since the constraint locator is
created in the middle of the bound hair, the locator is nearest the
bound area to be constrained.)
4 Change the hair display to the Current Position (Hair > Display > Current
Position).
5 Rewind to the start frame and play the simulation.
When the sphere passes through the bound curtain it collides with all
the bound hairs.
The bound part of the curtain relaxes within the first several frames, but
in the next steps you reset the position of those Start curves so they look
more natural at the beginning of the simulation.
