Explode Affector

Applies an explosive force to particles at birth.

Method #

This node applies a velocity to the affected particles at the birth of the particle. This is typically used to create explosion-like effects.

The Explode Mode attribute is used to determine if the particle should be pushed outwards from the affector’s position, or if it should be random for every particle. The magnitude of the velocity is controlled by the Velocity Scale attribute and modulated by a random value which is constant per particle and weighted by the Randomness attribute. The Affected Particle Amount parameter can be used to apply the effect only to a limited random subset of particles, where a value of 1 will cause every particle to be affected and 0 will affect no particles.

The velocity effect is weighted by a falloff calculated using the distance from the node to the particle. The effect ramps down from 100% to 0% at the distance specified by the Affected Radius attribute.

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
Velocity ScaleScale the strength of the affectors velocity on the particles.
Spread AngleChange the angle of spread for the particles.
RandomnessHow much randomness is added in the particles movement.
Affected RadiusThe radius within which particles will be affected.
Explode ModeWhere the explosion expands from.
  • From Emission Position : Explodes from the position of the explode node.
  • From Null Position : Explodes from a null input into the node.
  • Eurovision Splines (dont ask) : Self explanatory.
Explode ShapeChoose a shape the explosion spreads out in.
Affected Particle AmountWhat percentage of the particles are affected by the affector.
