PYROCLUSTER
REFERENCE 47
Regularity
Regularity set to 0% (left),
50% (center) and 100% (right).
Regularity controls the feathering of the rendered puffs. By default PyroCluster uses
primitive volumes to render the smoke or cloud effect. To remove visible edges, use
the Regularity value. A value of 100% will create sharp volume edges while a value
of 0% will create feathered volumes.
Grow Radius
Grow Radius set to 0% (left)
and 100% (right).
Most of the time you’ll probably want the noise to grow with the volume — tiny little
wisps just wouldn’t do for a huge volcano cloud. Grow Radius controls the amount
of scaling used for the effect. A value of 100% means that the noise structure grows
at about the same rate as the volume itself. For best results, and for a more turbulent
life, use values between 65% and 80%.
Scale
Scale set to 50% (left),
200% (center) and 1000% (right).
The Scale value controls the size of the noise pattern. Smaller values result in ner
patterns. Experiment with each scene to nd the best value for Scale, which could be
anything ranging from 0% to 10,000,000%! It just depends on the scene.
