Perception Neuron Mocap Skeleton

Perception Neuron Mocap Skeleton

Control skeletal rigs from a Perception Nueron system.

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.


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.

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.

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.

Axis Neuron Server AddressThe address / IP of the Axis Neuron server providing the skeleton stream.
Axis Neuron Server PortThe port of the Axis Neuron server providing the skeleton stream.
Avatar IndexSelect the mocap actor to drive the skeleton.
Input Skeleton ScaleUniformly scale the size of the input mocap skeleton.
MirroredMirror the movements of the incoming mobcap data along the x axis.
Flip ZFlip the Z axis of the skeleton, to match a model with a flipped z axis.
