When generating images in ComfyUI, if the face appears awkward or distorted, you can use the Face Detailer node to improve facial quality.
After launching ComfyUI, open ComfyUI Manager and search for the ComfyUI Impact Pack to install it.
Copy the 1-FaceDetailer.json file fromComfyUI/custom_nodes/comfyui-impact-pack/example_workflows
and paste it intoComfyUI/user/default/workflows.
If an error occurs due to a missing model in UltralyticsDetectorProvider, open ComfyUI Manager and run “Install Missing Custom Nodes”, then install the Impact Subpack.
With the 1-FaceDetailer.json workflow loaded and active, add one “Load LoRA” node by placing it in an empty area of the workspace.
Connect the Model and CLIP outputs from the Load Checkpoint node to the inputs of the Load LoRA node.
〈Important: Read Carefully from This Point〉
The CLIP output from the Load LoRA node should be connected to both the positive and negative conditioning node inputs.
The Model output from the Load LoRA node must be connected to two locations:
The model reroute input of the FaceDetailer node
The model reroute input connected to the KSampler node
Please take a close look at the three dashed circles.
By connecting the nodes this way, the facial features from the LoRA are applied instead of the base model’s face, resulting in more detailed and refined facial results.
<About KSampler and FaceDetailer Toggle Options>
For the KSampler, it is recommended to use the step count, guidance (CFG), sampler, and scheduler values that are appropriate for the base model you are using.
Following the base model’s recommended settings generally produces the most stable results.
An important point here is to apply these base model–recommended values identically to both the KSampler and the FaceDetailer nodes. This helps maintain consistency and stability during the facial refinement process.
For the FaceDetailer node, it is recommended to leave most toggle options at their default values.
The default settings are already well-balanced for facial correction and usually do not require adjustment.
If you enjoy experimenting, consider saving the default FaceDetailer settings in a Note node first, then freely adjust the options to explore different results.
Hopefully this guide resolves your issue. If any part of the explanation feels unclear, feel free to copy and paste this article into an LLM and ask how to proceed with the installation. You should be able to get helpful guidance that way as well.
