comfyui-easy-sam3-tools

SAM3 Interactive BBox Editor

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.
