# SAX_Bridge [JP](README_ja.md) | [Key Features](#key-features) | [Installation](#installation) | [Dependencies](#dependencies) | [Node Reference](docs/nodes_en.md) | [MIT License](#license) **Build advanced workflows with fewer nodes. Smart trial-and-error with management nodes.** SAX_Bridge is a collection of custom nodes that fills the missing pieces in ComfyUI workflows. From loading checkpoints (or split-distribution diffusion models such as Anima: UNET + text encoder + VAE), CLIP, and LoRA to prompt processing, sampling, detailing, and output — all in a minimal set of nodes, enabling high-quality generation without complex configurations. A unique scene-based control system lets you batch-manage nodes and groups, quickly switch between configurations, and shorten your iteration cycle. --- ## Key Features ### Advanced image quality in one node — Detailer

> **SAX Loader → SAX Prompt → SAX KSampler → SAX Upscaler → SAX Enhanced Detailer → SAX Output** > Complete pipeline from generation to upscaling, detailing, and saving — in just 5 nodes. > *(checkpoint: ZUKI anime ILL)* Crops the mask region, runs i2i redraw, and blends back into the original image — **all in one node**. Differential Diffusion is built in, so boundary blending requires no separate adjustment. Simply append it to the end of your workflow to automatically refine areas prone to softness — faces, hands, text, and more. For even higher quality, choose **SAX Enhanced Detailer** to add Shadow Enhancement, Edge Enhancement, and Latent Noise injection. Both Detailer nodes include an optional **CFG Guidance Enhancement** feature — select a mode and adjust strength to improve detail rendering. | Mode | Target | Effect | |---|---|---| | `agc` | High CFG (5+) | Suppresses color saturation spikes via tanh soft-clipping | | `fdg` | High CFG (5+) | Emphasizes detail via frequency band separation | | `agc+fdg` | High CFG (5+) | Both of the above | | `post_fdg` | Low CFG (1–3) | Detail emphasis for low-step LoRA workflows (e.g. DMD2) | > **SAX Guidance** is also available as a standalone node for use before SAX KSampler or SAX Upscaler. > Guidance also supports **PAG (Perturbed Attention Guidance)** which works independently of CFG scale. ### Finishing touches — Finisher **SAX Finisher** applies post-processing effects and image quality adjustments to the final image. Place it between the Detailer and Output. | Effect | Parameter | Description | |---|---|---| | Color Correction | `color_correction` | Matches color distribution to a reference image | | Smooth | `smooth` | Reduces jaggies and oversharpened edges via high-frequency suppression | | Sharpen | `sharpen_strength` / `sharpen_sigma` | Unsharp Mask edge sharpening | | Bloom | `bloom` | Soft glow from bright areas for atmospheric lighting | | Vignette | `vignette` | Darkens edges to draw focus to the center | | Color Temp | `color_temp` | Warm (+) or cool (−) color temperature shift | | Grayscale | `grayscale` | ITU-R BT.709 monochrome conversion (applied last) | All parameters default to 0 / False (disabled). Effects are applied in the order listed above.

| > Switch scenes with a single click using **SAX Toggle Manager**. > Controls group visibility and widget values (grayscale, save) simultaneously. > Instantly switch from quick preview to full-quality output. A control node that toggles groups, subgraphs, nodes, and Boolean widgets — **no wiring, no execution required**. Save multiple scenes and switch the entire workflow configuration instantly with the ◀▶ button. Pre-register comparison patterns like "with/without LoRA", "with/without upscaling", or "cache on/off" to eliminate manual reconfiguration. [↑ Back to top](#sax_bridge) --- ### Text-guided masking with instant comparison — SAM3 Segmenter × Image Preview

> Broad positive mask for "hair" minus a negative mask for skin — precise hair-only segmentation. > Pass the mask to two **SAX Enhanced Detailer** nodes for parallel hair color variations. > Compare all results side by side with **SAX Image Collector + SAX Image Preview**. **SAX SAM3 Multi Segmenter** generates masks by specifying targets with text prompts. Combining positive (broad capture) and negative (exclusion) prompts achieves high-precision segmentation without manual masking or selection tools. The more conditions you stack, the more accurate the result — enabling fine per-part control (hair, face, ears, hands) in a single node. Pass the generated mask to **SAX Detailer** for refinement, then compare the original, mask, and result side by side in **SAX Image Preview** for fast parameter tuning feedback. [↑ Back to top](#sax_bridge) --- ### Per-branch mask tuning — Mask Adjust **SAX Mask Adjust** applies **grow/shrink → blur → threshold** to an input MASK in one shot. When you want to fan out the same SAM3 output to multiple downstream nodes ("larger for Detailer / smaller for NoiseInjector"), this lets you avoid running SAM3 multiple times. - `invert`: flip "white = target" to "white = protected" (e.g. protect SAM3-detected face, refine the rest) - `grow`: hard-edged dilation/erosion (same separable MaxPool used by SAM3) - `blur` + `threshold`: smooth, jaggy-free expansion/contraction (`blur=3.0, threshold=0.1` for smooth dilate, `0.9` for smooth erode) - `blur` alone: soft mask for KSampler's noise_mask The SAM3 `mask_grow` and this node's `grow` are additive. When fanning out, set SAM3 `mask_grow=0` and tune per-branch with this node for clearer intent. [↑ Back to top](#sax_bridge) --- ### Manage prompt variations as a binder — Text Catalog **SAX Text Catalog** stores named texts (prompts, negatives, fragments) inside a single node and assigns them to output slots via Relations. Switch between scene variations, share a common negative across multiple samplers, or organize text snippets by tags — without rewiring your workflow. - **Catalog → Item → Relation → Slot** four-element model lets you separate text storage from output routing - **Manager Dialog** with search, tag filter, and a wide text editor for batch authoring - **Hybrid tag input** with auto-normalization (trim + lowercase), favorite tags pinned to the front - **Tag-aware sorting** keeps related items grouped and matches the tag toggle order - Output empty string for unset / orphan Relations — drops cleanly into `SAX Prompt Concat` - Text editor supports **danbooru tag autocomplete** when [pythongosssss/ComfyUI-Custom-Scripts](https://github.com/pythongosssss/ComfyUI-Custom-Scripts) is installed (falls back to manual input otherwise) See [Node Reference: SAX Text Catalog](docs/nodes_en.md#sax-text-catalog) for full details. [↑ Back to top](#sax_bridge) --- ### Simplify complex wiring — Collector **SAX Node Collector** aggregates outputs from multiple nodes into one, keeping downstream wiring clean. Automatically detects and re-syncs when source slots are added, removed, or renamed — connections never break during workflow editing. **SAX Pipe Collector** acts as a switch that selects the first valid Pipe from multiple routes, enabling conditional branching through wiring alone. **SAX Image Collector** batch-combines multiple IMAGE outputs and passes them to SAX Image Preview for all-at-once comparison.

Install sam3: ```bash pip install git+https://github.com/facebookresearch/sam3.git ``` #### Windows: triton is required sam3 depends on [triton](https://github.com/triton-lang/triton), which was historically Linux-only. On Windows, install one of the following **before** installing sam3: | Environment | Command | |---|---| | PyTorch ≥ 2.7 + CUDA ≥ 12.8 | `pip install triton` | | Older PyTorch / CUDA | `pip install triton-windows` | `triton-windows` is a drop-in compatible wheel for Windows that bundles TinyCC and a minimal CUDA toolchain, so no additional setup is required. See [triton-lang/triton-windows](https://github.com/triton-lang/triton-windows) for details. If SAM3 fails to load at runtime, SAX_Bridge will display the underlying `ImportError` (e.g. `No module named 'triton'`) so you can diagnose which dependency is missing.
