SAM3DBody_Smooth - ComfyUI Built-in Node Documentation - ComfyUI

Smooth SAM3D Body Pose Data reduces frame-to-frame jitter in 3D body pose sequences by averaging motion over time. It applies full smoothing to camera and appearance data, while backing off on mesh geometry when the subject rotates quickly, so fast spins are not flattened.

Inputs

Parameter	Description	Data Type	Required	Range
`mhr_pose_data`	The MHR pose data sequence to smooth, containing model parameters, shape parameters, expression parameters, MHR70 keypoint layout, and related mesh data.	MHR_POSE_DATA	Yes	—
`strength`	Smoothing strength. 0 = raw, 1 = smoothed. (default: 1.0)	FLOAT	Yes	0.0 to 1.0 (step 0.05)
`method`	gaussian: symmetric weighted average, best general-purpose smoother. savgol: sliding polynomial fit, preserves sharp peaks. (default: “savgol”)	COMBO	Yes	”gaussian" "savgol”
`window`	Temporal window in frames (odd values). (default: 7)	INT	Yes	1 to 51 (odd values, step 2)
`rotation_threshold_degrees`	Disables smoothing for this root rotation rate (degree/frame) to preserve fast spins. 30° suits most content, low values might disable smoothing on ordinary jitter and silently impacts quality. 0 = disable. (default: 30.0)	FLOAT	Yes	0.0 to 90.0 (step 1.0)

Note: When strength is 0.0 or lower, or window is 1 or lower, the node returns the input data unchanged. The input must contain at least 2 frames and keypoint data; otherwise the node returns the input data unchanged. When rotation_threshold_degrees is 0.0, the rotation-based smoothing backoff is disabled.

Outputs
