Field Affector

Field Affector

Applies a different field's velocities to a field.

Method #

This node uses the velocities of a separate field system and applies them to the current field system. This allows for ink to be disturbed by the motion of air, without rendering the air itself. An Optical Flow node can also be connected in a 2D field system, to control the field from the motion of a video.

The outputs from this node are just its transforms, useful for having multiple nodes follow the same motions without controlling each of their transforms individually.

Parameters

These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

ParameterDetails
Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

ParameterDetails
Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Velocity ScaleScale the amount the input field affects the parent field system.
RandomnessThe randomness of the new velocities added to the simulation.

Inputs

NameDescriptionTypical Input
Field NodeThe field to be used by the affector. If no field is connected, this node wil not function.Field Root
Mask NodeMasks the areas in which the affector won’t apply.Image Plane
Affected EmittersControl which Emitters are affected by the Affector. By default, all emitters in the field system are affected.Primitive Emitter
Transform ModifiersApply the transforms of another node to this node.Null
Target NodeModifiy the rotations of the node to always direct the z axis towards the input.Null
Local Transform OverrideApply the transforms of another node to this node, relative to its parent.Null
