ComfyUI: Sampling and Scheduler Configuration

Demo summary
The creator shows the sampling process in ComfyUI, specifically demonstrating how to select the correct scheduler and set sampling steps to avoid face distortion.
Step-by-step
- Navigate to the sampling process section
- Select a scheduler from the drop-down list
- Set the sampling steps to nine
- Clone the extension repository into your custom nodes folder if the scheduler is missing
- Install the required Python dependencies
- Restart ComfyUI to refresh the scheduler list
Options
- Use the official custom Sigma method
Watch out for
- Using the official custom Sigma method often results in distorted, blurry, or deformed faces
- The specific scheduler required may not be in the default drop-down list without an extension
Tips
- Avoid the custom Sigma method for better results in face swapping
- Set sampling steps to nine based on extensive testing for optimal output
