Angled Motion Affector

Angled Motion Affector

Updated: 26 Mar 2025

Moves particles via a noise field, with directions that are constrained to an angle.

Method #

This node moves particles via a noise field, with directions that are constrained to an angle - allowing for example motions constrained to square patterns.

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 X The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local y-axis.
Scale Z The objects scale along the local z-axis.

Control the inheritance of the transforms from the parent.

ParameterDetails
Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Velocity Amount Amount of velocity to add to the particles movement.
Direction Angle Restriction Restrict the angle of which the motion will be applied. Restricts movement of the particle to certain angles.
Axis Axis on which to apply velocity.
  • 2D - YZ : Apply motion only along the Y and Z axis.
  • 2D - XZ : Apply motion only along the X and Z axis.
  • 2D - XY : Apply motion only along the X and Y axis.
  • 3D : Apply motion along the X,Y and Z axis.
Speed Variation How much variation there is in the speed each time the particle direction changes.
Position Random Scale The probability that the direction will change based on “Direction Change Rate - Position”.
Time Random Scale The probability that the direction will change based on “Direction Change Rate - Time”.
Direction Change Rate - Position TBC
Direction Change Rate - Time The rate at which the particles will change direction based on time. Lower value means the direction will change less frequently.
Randomness Sets random speeds for each particle. Will stay consistent for the life of the particle
Life Effect Coeffs How 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.
Radius Radius of the affector’s falloff.
Inner Radius Inner radius off the affectors falloff.
Falloff Shape Select which method to calculate the falloff.
  • Point : Falloff is drawn outward from a point.
  • Line : Falloff is drawn outward from a Line .
  • Plane : Falloff is drawn outward from a plane.
