Perception Neuron Mocap Skeleton
Updated: 15 Sep 2026
Control skeletal rigs from a Perception Nueron system.
Perception Neuron Mocap Skeleton
Method #
This node reads bone data from a Perception Neuron motion capture suit and applies it to Bone nodes, either via direct input links or by a connection to the root of the target hierarchy. A network connection must be made to the Axis Neuron software which provides a stream of bone data from the suit. The server address and port must be entered to match the output address and port in Axis Neuron. If there is no connection the node will be hatched out in red.
The input skeleton the node is applied to must have been designed to receive motion capture data: the bones must be named, oriented and arranged appropriately. Mixamo rigs are a good reference.
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.

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.

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 Axis Neuron Server Address
The address / IP of the Axis Neuron server providing the skeleton stream.
Axis Neuron Server Port
The port of the Axis Neuron server providing the skeleton stream.
Avatar Index
Select the mocap actor to drive the skeleton.
Input Skeleton Scale
Uniformly scale the size of the input mocap skeleton.
Mirrored
Mirror the movements of the incoming mobcap data along the x axis.
Flip Z
Flip the Z axis of the skeleton, to match a model with a flipped z axis.
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.
