Particle Bone Deformer
Updated: 3 Feb 2025
Deforms geometry by allowing Particle Affectors to apply to the mesh bones
Particle Bone Deformer
Method #
This node uses the forces from a particle system to affect the bones or chunks of an imported 3D Object.
Connect Particle Affector nodes as children to the Particle bone node to have them apply to the parent mesh.
Parameters
These properties control the core behaviours of the node.
Parameter Details Physics Velocity Dampening
Dampen the changes in velocity applied to the vertices for smoother movement.
Fixed Update Rate Enabled
Force the deformer to update at a fixed rate.
Fixed Update Framerate
Choose what framerate the deformer is updated at. Only functions with Fixed Update Rate enabled
Terminal Velocity
The maximum speed the deformer can move at before the mesh is distorted.
Motion Smoothing
How much motion smoothing is done to the deformer.
These properties control how the particle motion applies to the mesh.
Parameter Details Deformer Amount
How much the particles affect the deformer.
Deformer Velocity Amount
How much the particle velocities affect the deformer.
Rotation Velocity Amount
How much the vertices are rotated along with their velocities.
Rotation Randomness
How much randomness is applied to their rotation speeds.
Sub-Bone Separation Start
Distance at which the sub-bone separation begins.
Sub Bone Separation Randomness
Randomness in the sub-bone separation.
Source Mode
Select which part of the source mesh to deform based on.
- Mesh Bones : The vertex deformations are applied to the armature bones of the mesh. A rigged mesh must be used for this to function.
- Mesh Chunks : The vertex deformations are applied to the separated mesh pieces.
