comfyui-easy-sam3-tools
Custom nodes for building SAM3-centric editing pipelines inside ComfyUI, featuring mask merging, bounding box rendering, and DOM-based interactive editing. (Description by CC)
Nodes (6)
Your pose data won't plug into the OpenPose Editor? This is the adapter.
Grab one frame out of a pose sequence without mutilating your graph.
See what your boxes actually look like before SAM3 ever runs.
Draw SAM3 boxes with your mouse instead of typing JSON coordinates.
SAM3 gives you one mask per object. Pick the ones you care about.
The multiply node that shipped with the pack for no particular reason.
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.
