Use this setting to determine if the splines should be checked for collision with other objects containing a Hair Collision tag.
Activate this setting to stiffen the springs connecting the mass points. The spline will try to maintain its shape without simply falling/collapsing, as it would if this option were not active. The splines will sway at or near their initial state, depending on rigidity.
Use this setting to define a starting point for the spline dynamics effect. This setting can also be used if, for example, the splines have fallen as a result of dynamics and you want to save the resulting state.
