ComfyUI Impact Pack
ComfyUI Impact Pack is a custom node pack for ComfyUI that detects faces and objects in an image and regenerates them in finer detail.
ComfyUI Impact Pack is a free custom node pack by ltdrdata for people building image workflows in ComfyUI. Its Detector nodes find regions such as faces, people or objects as bounding boxes or segmentation masks, using ONNX models, CLIPSeg or Segment Anything, including SAM2 for tracking across video frames. Detailer nodes, including FaceDetailer, crop each detected region, regenerate it at higher resolution and paste it back, which repairs small faces and fine details. The pack also has upscaler nodes, Pipe nodes that bundle model, prompt and sampler connections to keep graphs tidy, regional samplers and a wildcard processor for varied prompts. It supports FLUX.1 models, installs through ComfyUI-Manager, and YOLO detection through Ultralytics comes from the separate Impact Subpack. The code is GPL-3.0 licensed.
