Inputs
The pGradient Force node accepts two inputs: the default orange input from a particle node
and one from a bitmap image with an Alpha channel gradient. A magenta or teal 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.
Input: The green input takes the 2D image that contains the Alpha channel gradient.
Region: The magenta or teal 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 gradient force occurs.
Basic Node Setup
The pGradient Force node is placed in between the pEmitter and pRender nodes. A Fast Noise
node is used to create the Alpha gradient used to modify the velocity of the particles.

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.
Strength
Gradient Force has only one specific control, which affects the strength of the force and
acceleration applied to the particles. Negative values on this control will cause the Gradient
Force to be applied from black to white (low values to high values).
