Shockwave Affector
Updated: 16 Jun 2026
Apply a shockwave through particles.
Shockwave Affector
Method #
This node applies a pulsing spatial shockwave through particles. The shockwave moves outward from the emission point, and pushes and pulls the particles it comes in contact with.
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.
Parameter Details 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.
Parameter Details 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.
Parameter Details Velocity Scale
Scale the strength of the affectors velocity on the particles.
Simulation Speed
Speed at which the simulation is played.
Wave Size
The strength of the wave.
Wave Delay
The rate at which new shockwaves are created.
Travel Speed
The speed at which the wave moves.
Wave Offset
The time offset of the first wave.
Radius
The radius of effect of the affector.
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.
These properties are used to set the falloff of the node.
Parameter Details Falloff Mode
Which shape to use to calculate the falloff.
- Off : No falloff is used. Everything will be affected equally.
- Spherical : Falloff is drawn outward from a central point, forming a spherical falloff.
- Cylindrical : Falloff is drawn outward from a line, forming a cylindrical falloff.
- Planar : Falloff is drawn outwards in one or both directions from a plane, forming a planar falloff.
- Procedural : Uses a connected procedural system to describe the falloff area. A procedural system must be input for this property to function.
- Cubic : Falloff is drawn from the sides of a cube.
Falloff Axis
Which axis the falloff should be oriented on.
Falloff Direction
When using Planar mode, which directions to use to calculate the falloff.
- Bidirectional : The falloff applies in both directions from the plane.
- Negative : The falloff applies only in the negative direction from the Fallof Axis. The positive direction has the full effect applied.
- Positive : The falloff applies only in the positive direction from the Fallof Axis. The negative direction has the full effect applied.
Falloff Easing Mode
Interpolation method used to calculate the falloff within its range of influence.
- Linear : Falloff reduces linearly across the falloff range.
- Sine : Falloff reduces using a sine function across the falloff range.
- Quadratic : Falloff reduces using a quadratic function across the falloff range.
- Cubic : Falloff reduces using a cubic function across the falloff range.
- Circular : Falloff reduces using a circular function across the falloff range.
- Bounce Back : Falloff uses a function which as values reach the edge of the falloff range, they will overshoot and bounce back.
- Elastic : Falloff uses a function similar to bounce back, but the value will initially move in the opposite direction, creating a “pull and release” effect.
Falloff Size X
Size of the falloff range along the X axis.
Falloff Size Y
Size of the falloff range along the Y axis.
Falloff Size Z
Size of the falloff range along the Z axis.
Outer Range
Outer range of the falloff, outside of which the falloff is no longer effective.
Inner Range
Inner range of the falloff, inside of which the falloff is fully effective.
Curve Power
Controls the rate of change for the falloff between the inner and outer range.
Invert
Inverts the effect of the falloff.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
