Explosion
Strength, Decay, Variation
Strength denes the force used to accelerate the clusters. The value needed for a good effect depends
on the size and density of the clusters. Use Decay to set a fall-off for the Strength. 0% means no
fall-off, 100% means the Strength falls to 0 by the time it reaches the edge of the blast range. Use
Variation to vary the Strength for each cluster. 0% means no variation, 100% means the Strength can
vary from zero to twice its entered value.
Direction
This sets the direction in which clusters can be accelerated — along all axes, along two axes, or along
one axis only. Use Variation to vary the direction of each cluster. This helps you avoid uniform shapes
to the explosion. If you have set Direction to a single axis, enable Linear if you want equal force to be
applied to all clusters.
Blast Time
Like Strength, this affects the amount of force applied to the clusters. Change this value only if the
maximum Strength value is insufcient.
Blast Speed, Decay, Variation
Here, enter the blast speed (in metres per second). A cluster remains in place until the blast (green
frame) reaches it. If you set Blast Speed to 0, all clusters are accelerated immediately. Use Variation to
vary the Blast Speed value. Decay sets fall-off for the Blast Speed. 0% means no fall-off, 100% means
the Blast Speed falls to 0 by the time it reaches the edge of the blast range.
If the gravity range (blue frame) is larger than the blast range (red frame), the
Decay value refers to the gravity range instead.
