comfyui-easy-sam3-tools
Custom nodes for building SAM3-centric editing pipelines inside ComfyUI. They pair well with comfyui-easy-sam3 and comfyui-kjnodes, letting you harness SAM3’s zero-shot segmentation accuracy for precise masks that can drive local inpainting, editing, or any downstream compositing task.
Nodes
| Node | Description |
| ---- | ----------- |
| Sam3MaskRangeSelector | Consumes ordered SAM3 obj_masks, extracts a configurable slice (take_start, take_count), and merges the selection into a single mask per frame for focused edits. |
| Sam3DrawBBox | Renders SAM3 / VLM bounding boxes over image tensors. Accepts JSON strings, {boxes: [...]} payloads, tensors, or per-batch lists, normalizes them, then emits an overlayed tensor. |
| Sam3InteractiveBBoxEditor | DOM-based bbox editor widget. Streams the upstream image, lets you author/adjust boxes interactively, and outputs KJ-format bounds alongside the passthrough image for subsequent SAM3 inference. |
Installation
Drop the folder inside ComfyUI/custom_nodes/, then restart ComfyUI.
