Inputs
The pAvoid 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 particles avoid.
Basic Node Setup
The pAvoid node is placed in between the pEmitter and pRender. A Shape 3D node is used to
create the region the particles will avoid.

Inspector
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.
Distance
Determines the distance from the region a particle should be before it begins to move away
from the region.
Strength
Determines how strongly the particle moves away from the region. Negative values make the
particles move toward the region instead.
