This value defines the state of the explosion. 0% is the start of the explosion, 100% is the end of the explosion. To change this value interactively, drag the orange handle in the viewport (at the default value of 0%, the orange handle is at the Explosion object’s origin).
This value defines the speed with which the polygons are prepelled from the center of the explosion. If Speed is set to 100 cm and Strength is set to 10%, the polygons will travel this maximum distance in centimeters
This value defines the angle through which each polygon rotates during the entire explosion. The direction of the rotation axis for each polygon is random and changes over the course of the explosion.
This value defines the relative size of each polygon at the end of the explosion. If the value is set to 1, the polygons will remain the same size throughout the explosion. If the value is set to 0, the polygons will disappear by the end of the explosion. If the value is 2, the polygons will double in size.
This value defines the percentage by which the speed and angle speed may vary.
