pVortex Node

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.

pVortex Node 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.

pVortex Node Setup

The pVortex node is placed in between the pEmitter and pRender nodes

pVortex Node Controls

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
This control determines the Strength of the Vortex Force applied to each particle.

Power
This control determines the degree to which the Strength of the Vortex Force falls off with distance.

X, Y, and Z Offset
Use these sliders to set the amount by which the vortex Offsets the affected particles.

Size
This is used to set the Size of the Vortex Force.

Angle X and Y
These sliders control the amount of rotational force applied by the Vortex along the X and Y axes.
