Randomize
The Random Seed slider and Randomize button are presented whenever a Fusion node relies
on a random result. Two nodes with the same seed values will produce the same random
results. Click the Randomize button to randomly select a new seed value, or adjust the slider to
manually select a new seed value.
X, Y, and Z Strength
The Strength control affects the amount of chaotic motion imparted to particles.
Strength Over Life
This LUT control can be used to control the amount of turbulence applied to a particle
according to its age. For example, a fire particle may originally have very little turbulence
applied at the start of its life, and as it ages, the turbulence increases.
Density
Use this control to adjust the density of the turbulence. Higher values will produce finer
variations in the turbulence produced.
Common Controls
Conditions, Style, Region, and Settings Tabs
The Conditions, Style, Region, and Settings tabs are common to all Particle nodes, so their
descriptions can be found in “The Common Controls” section at the end of this chapter.
pVortex [pVt]
The pVortex node
pVortex Node Introduction
The pVortex node applies a rotational force to each particle, causing them to be drawn toward
the source of the Vortex. In addition to the Common Particle Controls, the pVortex node also
has the following controls.
Inputs
The pVortex node has a single orange input by default. Like most particle nodes, this orange
input accepts only other particle nodes. A green bitmap or mesh input appears on the node
when you set the Region menu in the Region tab to either Bitmap or Mesh.
Input: The orange input takes the output of other particle nodes.
Region: The green or magenta region input takes a 2D image or a 3D mesh
depending on whether you set the Region menu to Bitmap or Mesh. The color of
the input is determined by whichever is selected first in the menu. The 3D mesh or a
selectable channel from the bitmap defines the area of the vortex.
