ParticleFieldForce

The ParticleFieldForce node applies various forces to particles based on an input field. It can be used to accelerate particles, rotate or orient them, bounce them off surfaces defined by signed distance fields, or kill them according to field density.

Note: This is a LABS node, indicated in Nuke with the tag:
LABS nodes are experimental and not intended to be used for production.

Inputs and Controls

Connection Type	Connection Name	Function
Input	fld	An input for connecting to field that you wish to attract or repel from.
	particles	An input for connect particles.

Control (UI)	Knob (Scripting)	Default Value	Function
ParticleFieldForce Tab
display	display	unchanged	Adjust the display characteristics of the particles. These settings don’t affect the render output of the scene; these are for display purposes only in the 3D Viewer. • off - hides the particles. • wireframe - displays only the outlines of the particle. • solid - displays all particles with a solid color. • solid+wireframe - displays the particles as solid color with the particles outlines. • textured - displays only the surface texture. • textured+wireframe - displays the wireframe plus the surface texture. • unchanged - doesn't change the particles display mode. The Viewer can override this setting.
selectable	selectable	on	Turn off to prevent picking with the mouse in the Viewer.
render	render_mode	unchanged	Sets how the particles will render. This control is independent from the display selection, but has the same settings.
Operation	attribute	Force	Specify the type of operation to affect the particles.
Strength	strength	1	Sets the strength of the attraction, measured in inverse square. A negative value is an attraction and a positive value is a repulsion.
