pFriction [pFr]
pFriction Node Introduction
The pFriction node applies resistance to the motion of a particle, slowing the particle’s motion
through a defined region. This node produces two types of Friction. One type reduces the
velocity of any particle intersecting/crossing the defined region, and one reduces or eliminates
spin and rotation.
Inputs
The pFriction node has a single orange input by default. Like most particle nodes, this orange
input accepts only other particle nodes. A green or magenta 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 where the friction occurs.
Basic Node Setup
The pFriction node is placed in between the pEmitter and pRender. A Shape 3D node is used
to create the region the particles bounce off.
