Mocap Stream
Updated: 27 Mar 2024
Use recorded Mocap Data
Mocap Stream
Method #
This node allows a pre-recorded motion capture data stream to be used as a proxy / replacement for live motion capture data on the Perception Neuron Mocap Skeleton node. When this node is connected to the Perception Neuron Mocap Skeleton’s “Mocap Stream” input, it overrides live data.
The node requires a motion capture data stream to be set via the “Mocap Stream” parameter. This stream should either be a BVH file loaded as a “BVH Animation” resource, or data recorded from Perception Neuron loaded as a “Perception Neuron Mocap Stream” resource.
Parameters
{message-information-attributes
Parameter Details Mocap Stream
The mocap stream resource.
Active
Determines whether the node is active and its data should be used.
Time Mode
Change how the stream is sampled with respect to the scene’s playback time.
- Use Deltas (Continuous/Looping) : The time runs based on the frame delta, loops when the play head loops, and the Playback Rate parameter may be animated.
- Locked To Timecode : The time is locked to the time code. The Playback Rate parameter may not be animated.
- Timecode (Animatable Playback Rate) : The time is tied to the time code, but the Playback Rate parameter may be animated.
Time Offset
The time offset for the animation.
Playback Rate
The playback rate of the animation.
Interpolation
The interpolation mode for the animation’s keyframes.
- Stepped : Jump from between gaps in Mocap data.
- Linear : Use linearly interpolate between gaps in Mocap data.
- Cubic : Use cubic interpolation between gaps in Mocap data.
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.

| Parameter | Details |
|---|---|
| Duration |
Control the duration of 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). |

| Name | Description | Typical Input |
|---|---|---|
| Active | Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance. | Value |
