Explode Affector
Applies an explosive force to particles at birth.
Explode Affector
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.
Parameter Details Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z 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.
Spread Angle Change the angle of spread for the particles.
Randomness How much randomness is added in the particles movement.
Affected Radius The radius within which particles will be affected.
Explode Mode Where 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 Shape Choose a shape the explosion spreads out in.
Affected Particle Amount What percentage of the particles are affected by the affector.
