This custom node is created by decomposing and porting the WanVideo UniAnimate pose detector node from kijai's ComfyUI-WanVideoWrapper. The key difference is that instead of using image inputs, it now accepts KeyPoint data as input, enabling manipulation of body types that cannot be estimated by the pose detector alone.

Additionally, the Openpose Editor node from toyxyz/ComfyUI-ultimate-openpose-editor has been similarly decomposed and ported, enabling fine-tuning of individual parts.

Features

Node Overview

ProportionChanger Pose Detector: Detects KeyPoints from images
ProportionChanger Reference: Transforms proportions to reference poses
ProportionChanger Pose Render: Converts KeyPoints to images
ProportionChanger Params: Adjusts parameters for individual KeyPoint parts, including separate upper/lower arm, thigh/lower-leg, and feet scaling
ProportionChanger Interpolator: Interpolates KeyPoint videos with in-betweening
PoseData to pose_keypoint: Converts WanAnimate POSEDATA into POSE_KEYPOINT
pose_keypoint resize: Resizes POSE_KEYPOINT to a target size (pads then scales to avoid stretching when aspect differs)
pose_keypoint input: Converts JSON text to KeyPoints
pose_keypoint preview: Converts KeyPoints to JSON
(Down)Load Mascot Pose Model: Downloads and loads a mascot pose ONNX model from HuggingFace
(Down)Load Mascot BBox Model: Downloads and loads a mascot bbox ONNX model from HuggingFace
Mascot Pose Detector: Detects mascot body pose as POSE_KEYPOINT
Mascot BBox Detector: Detects mascot part bounding boxes as BOUNDING_BOX
pose_keypoint to SCAIL-Pose: Converts 25-point POSE_KEYPOINT to SCAIL-Pose data

Installation

Install via ComfyUI Manager

Search for "ComfyUI-ProportionChanger" in ComfyUI Manager's Custom Nodes Manager and install
Restart ComfyUI

Manual Installation

Clone this repository into your custom_nodes folder:

cd ComfyUI/custom_nodes
git clone https://github.com/grmchn/ComfyUI-ProportionChanger.git

Install dependencies:

cd ComfyUI-ProportionChanger
pip install -r requirements.txt

Restart ComfyUI

Usage

Basic Workflow

Please refer to example_workflows.

proportion_changer_basic2

Converting WanAnimate POSEDATA

Use WanAnimatePreprocess "Pose and Face Detection" to produce POSEDATA
Feed POSEDATA, width, and height into PoseData to pose_keypoint
Connect the resulting pose_keypoint to ProportionChanger Reference / Render nodes
Example workflow: example_workflows/proportion_changer_pose_data_to_pose_keypoint.json

Converting to SCAIL-Pose

Connect a changed POSE_KEYPOINT to pose_keypoint to SCAIL-Pose
Use the resulting DWPOSES with SCAIL-Pose workflows
Example workflow: example_workflows/proportion_changer_SCAIL_pose.json

Troubleshooting

Common Issues

Model Loading Errors: Models should be automatically downloaded from HuggingFace. Please ensure pose models are in the correct directory.
Incorrect body proportions after transformation with reference image: The pose_keypoint and reference_pose_keypoint aspect ratios (canvas width/height) may not match. ProportionChanger Reference has auto_resize_reference (default ON) to automatically align the reference to the pose canvas size. If needed, use pose_keypoint resize to explicitly align width/height. Fine-tune individual body parts using the "ProportionChanger Params" node.
Nothing displays after transformation with reference image: The reference image's pose estimation has failed. Use OpenposeEditor or similar tools to input parameter values manually.

Mascot Pose Models

Mascot pose nodes download model artifacts from grmchn/mascot-pose-detect on HuggingFace into ComfyUI/models/mascot_body_detect. The official model package is Apache 2.0 and uses the keypoint/dinov2_vitpose_l_v2 variant by default. The previous keypoint/dinov2_vitpose_l variant remains available in the same model repository. The node code remains part of this repository, and use of the downloaded models is subject to the model package license.
