Scale Affector

Scale Affector

Apply changes to the scale of particles.

Method #

This node changes the scale of particles as they enter its falloff region.

All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain.

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
Scale AmountHow much to scale all particles by.
RadiusAlter the outer radius at which the affector is no longer effective.
Inner RadiusAlter the inner radius up to which the affector is fully effective.
RandomnessHow much randomness is added in the particles movement.
Blend ModeHow the changes to the Scale Amount will affect the particles.
  • Blend : Multiplies the Scale Amount and the current particle scale.
  • Add : The Scale Amount will be added to the current value.
  • Subtract : The Scale Amount will be subtracted from the current value.
  • Max : The larger value between the Scale Amount and the current particle size is chosen.
  • Min : The smaller value between the Scale Amount and the current particle size is chosen.
Falloff ShapeSelect which shape to calculate the falloff from.
Life Effect CoeffsHow much the particles are affected by the affector at different stages of the particles life cycle. Values 1 and 2 are control points used to control a bezier curve between values 0 and 3.
