User Manual

Change Sets
This option allows the user to change the particle’s Set to become influenced by forces other
than the original particle. See “The Common Controls” in this chapter to learn more about Sets.
Style
This option allows the user to change the particle’s Style and thus the look. See “The Common
Controls” in this chapter to learn more about Styles.
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.
pCustom [pCu]
The pCustom node
pCustom Node Introduction
The pCustom node is used to create custom expressions that affect the properties of particles.
This node is similar to the Custom node, except the calculations affect particles rather
than pixels.
Inputs
The pCustom node has three inputs. Like most particle nodes, this orange input accepts only
other particle nodes. The green and magenta inputs are 2D image inputs for custom image
calculations. Optionally, there are teal or white bitmap or mesh inputs, which appear 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.
–
Image 1 and 2: The green and magenta image inputs accept 2D images that are
used for per pixel calculations and compositing functions.
–
Region: The teal or white 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 where the custom particle node
takes effect.
