This (blue) frame denes the area in which gravity has an effect. However, all clusters inside the blast
range (red frame) will be affected by gravity regardless. Use Variation to prevent a perfect sphere of
gravity.
Rotation
Speed, Decay, Variation
Speed denes the speed of rotation of the clusters. A negative value reverses the direction of rotation.
Decay controls fall-off for the Rotation value. 0% means no fall-off, 100% means the Rotation value
falls to 0 as the clusters reach the edge of the blast range. Use Variation to vary the rotation for each
cluster.
Rotation Axis, Variation
By default, each cluster rotates about its center of gravity. Here, you can make clusters rotate around
the X-axis, Y-axis or Z-axis only of the world system. This is useful for special effects, logo animation
and so on. Use Variation to tumble the clusters.
Special
Wind, Variation
The Wind value denes the strength of the wind effect. The wind blows in the direction of the
exploding object’s Z-axis. Use Variation to vary the wind for each cluster.
Wind does not take object weight into account.
