Separates guide curves into one interpolation group per curve. Render hairs are not interpolated between guide curves that belong to different interpolation groups. Instead, half the render hairs between the guides follow one guide and the other half follow the other guide.
To see which guide curves belong to which interpolation group, turn on Hair Interpolation Group IDs in the Objects.
To apply: Select at least one point on each of the guide curves you want to shatter, and then choose Modify 
Interp Shatter from the Hair panel.
To display: Select the hair object, click the Selection button on the Select panel, and then click the Hair Shatter Operator icon.
