ComfyUI Extension: ComfyUI-ProportionChanger

ComfyUI-ProportionChanger Introduction

ComfyUI-ProportionChanger is an innovative extension designed to enhance your creative workflow by allowing you to manipulate and adjust the proportions of poses in your AI-generated images. This tool is particularly useful for AI artists who want to have more control over the body proportions in their artwork, enabling them to create more dynamic and personalized compositions. By using keypoints, which are specific points on a body that define its pose, this extension allows you to adjust these points to change the overall proportions of the figure. This can solve common issues such as disproportionate body parts or awkward poses, providing a more refined and polished final image.

How ComfyUI-ProportionChanger Works

At its core, ComfyUI-ProportionChanger works by detecting keypoints in an image, which are then used to define the pose of a figure. Think of keypoints as a digital skeleton that you can adjust to change the figure's posture and proportions. The extension uses a series of nodes to process these keypoints, allowing you to input, adjust, and render them into a final image. For example, if you have an image where the arms are too short, you can use the ProportionChanger to extend the arm keypoints, thus lengthening the arms in the final render. This process is akin to adjusting a mannequin's limbs to achieve the desired pose.

ComfyUI-ProportionChanger Features

ComfyUI-ProportionChanger offers a variety of features to help you customize and perfect your images:

• ProportionChanger DWPose Detector: This feature detects keypoints from an image, serving as the foundation for any adjustments you wish to make.
• ProportionChanger Reference: Allows you to convert a reference pose into a new set of proportions, making it easier to replicate or modify existing poses.
• ProportionChanger DWPose Render: Converts the adjusted keypoints back into an image, allowing you to see the results of your modifications.
• ProportionChanger Params: Offers fine-tuning capabilities for each keypoint, enabling precise adjustments to individual body parts.
• ProportionChanger Interpolator: This feature interpolates between keypoints in a video, creating smooth transitions and animations.
• pose_keypoint input and preview: These nodes allow you to convert JSON text into keypoints and vice versa, providing flexibility in how you manage and store pose data.

What's New with ComfyUI-ProportionChanger

Recent updates have introduced several enhancements to the extension:

• Pose Keypoints to Mask Node: Added on June 3, 2025, this feature allows you to create masks from pose keypoints, offering more control over specific areas of your image.
• Translate X, Y, and Rotation: Introduced on June 2, 2025, these options provide additional ways to manipulate the position and orientation of your keypoints.
• Target Keypoint Scaling: Added on May 28, 2025, this feature allows you to scale keypoints relative to a target, offering more nuanced control over proportion adjustments. These updates enhance the flexibility and precision of the extension, making it an even more powerful tool for AI artists.

Troubleshooting ComfyUI-ProportionChanger

Here are some common issues you might encounter while using ComfyUI-ProportionChanger, along with solutions:

1. Model Loading Error: Ensure that the DWPose model is correctly downloaded from HuggingFace and placed in the appropriate directory.
2. Proportion Issues After Transformation: If the body proportions appear incorrect after using a reference image, make sure the reference image is the same size as the pose image. Use the "ProportionChanger Params" node for fine-tuning.
3. No Output After Transformation: This may occur if the DWPose fails to estimate the pose from the reference image. Consider using the Openpose Editor to manually input parameter values.
