SAM3 Inpaint (FaceDetailer, ADetailer like)

This workflow functions similarly to FaceDetailer or ADetailer.

SAM3 identifies the target area, and the Inpaint node regenerates it.

1. A Single Unified Model

- Instead of using SAM2 combined with multiple bounding box (bbox) and segmentation models (segm), this process uses just one model for all body parts and clothing.

- You can select almost anything: from hands, legs, and feet to nails, earrings, and more.

- Simple Implementation: Most basic body parts have dedicated prompt nodes. Simply select a tag from the "Preset List For --->" and paste it into "Preset Area" (Ctrl+C / Ctrl+V).

- Customization: If you need something not included in the presets, disable "Preset Area" and enable "Custom Area", then enter your prompt in the field at the bottom of the group.

- Note: Only one mode should be active at a time: either "Preset Area" or "Custom Area."

2. Detection Control

- You can adjust the detection confidence threshold using the "SAM3 % Detection" slider.

- For paired features (such as eyes, hands, or legs), you can specify the number of areas to find using the "SAM3 Number Of Detected" node.

- Nuance: When selecting multiple objects, sequential generation (processing one hand and then the other) is not supported. It will either regenerate both hands simultaneously or a single hand (depending on the "SAM3 % Detection" setting).

3. Mask Refinement

- You have full control over the mask: you can change its size, add blur, and smooth out the edges for better blending.

4. Integrated LoRAs and Prompts

- The Inpaint node features four dedicated LoRA slots. It also includes a universal negative prompt field that remains consistent regardless of the specific body part or clothing being processed.

Compatibility:

The workflow is optimized for SDXL. However, you can easily adapt it for other models by connecting the outputs of the new nodes to the corresponding "Get nodes."
