Defines the state of the shatter deformation. 0% is the start of the shatter effect (no shattering), 100% is the end (pieces shattered and lying on the ground). To change this value interactively, drag the orange handle in the viewport.
Defines the angle through which each polygon rotates during the entire shatter deformation.
Defines the relative size of each polygon at the end of the shatter deformation (when Strength is 100%). If the value is set to 1, the polygons will remain the same size throughout the deformation. If the value is set to 0, the polygons will disappear by the end of the shatter effect. If the value is 2, the polygons will double in size.
Defines the percentage by which the individual polygon speeds may vary from the perfect, uniform value.
