    Features

    TBG Enhanced Tiled Upscaler and Refiner Pro is an advanced, modular enhancement suite for tiled image generation and refinement in ComfyUI. It introduces neuro generative tile fusion, interactive tile-based editing, and multi-path processing pipelines designed for extreme resolution workflows up to but not limitet to 100MP, high fidelity, and adaptive post-generation control.

    • AI Image Enhancement: Applies advanced algorithms to improve visual quality.
    • High-Resolution Generation: Creates images with greater clarity and fine detail.
    • Image Polishing: Enhances visuals for a smooth, finished appearance.
    • Neuro-Generative Tile Fusion: Seamlessly fuses image tiles into a coherent whole.
    • User-Friendly Interface: CE version built for straightforward and intuitive use, Pro version offers advanced customization.

    1. New Fusion Techniques

    TBG Enhanced Tiled Upscaler and Refiner Pro introduces tree next-generation tile fusion processes that go far beyond traditional blending:

    Soft Merge CE

    Choose between adaptive blending strategies compatible with common upscalers like USDU,and others. It intelligently handles tile compositing recommended for low denoise workflows. A quick and solid method for getting consistent, high-quality upscales but limited in x factor.

    PRO Neuro-Generative Tile Fusion (NGTF)

    An advanced generative system that remembers newly generated surroundings and adapts subsequent sampling steps accordingly. This makes high-denoise tile refinement possible while maintaining:

    • Global consistency / color / strukture/ now need vor blended borders / no seams
    • Sharp, coherent details
    • Memory of contextual relationships across tiles
    • Adds the possibility to generate tiled ultra high res images
    • Seamless result's while adding high amount of new details and creative freedom. Ideal for transforming your image into something new and elevated, without simply recreating what was already there.

    2. Design Suite

    TBG_Enhanced isn’t just about quality — it’s about flexible, curated, and controlled image refinement, where the art director guides the outcome, not the algorithm.

    One-Tile Preview & Smart Presets

    Quickly generate single-tile previews to fine-tune the right settings before running the full job. Presets adapt intelligently to image dimensions and desired resolution.

    Post-Sampling Tile Correction

    You can resample only the tiles you don’t like — no need to regenerate the full image. This allows:

    • Precision editing
    • Fixing small errors without full reprocessing

    Resume Tile Refinement

    Modify or refine individual tiles days later while keeping the original input image and final result. The system supports:

    • Saved all single tiles for postproduction
    • Re-injection of noise and conditioning over single tiles

    3. Pipeline Structure

    TBG_Enhanced is powered by a flexible pipeline architecture built around tile-aware processing paths:

    TBG Tile Prompter Pipe

    Access prompt and denoise settings per tile. Enables:

    • Per-tile Promt editing
    • Denoising strength by tile

    TBG Tile Enrichment Pipe

    Control multiple sampling and model-level features:

    • Model-side: Use DemonTools for additional detail creation
    • Sampler-side: Inject custom noise at specific steps, or apply a noise injection curves to enhance you image in a more creative way.
    • Sampler-internal: Enable per-step sampler-side noise injection eta - gives rhe sampler on each step new addition noise to keep reinventing and defining detail
    • Built-in noise reduction: A preprocessing step that softly blurs the image before refinement begins, allowing the model more freedom to generate improved results—especially on broken, noisy, overly sharp, or imperfect inputs.
    • Optional tile up/downscaling during sampling to scale higher detailed content and extra sharp final image results

    ControlNet Pipe

    Tiled generation now supports unlimited ControlNet inputs per tile, unlocking:

    • High-resolution conditioning
    • Fine-grained control for large images
    • Targeted structure, depth, edge, pose, or segmentation maps for each region

    changlog 1.06 alfa V2.1 add Python 3.13 support for ComfyUI 0.3.50

    changlog 1.06 alfa V2

    -Added TBG Detail Enhancer node

    -Modified TBG Magnific Magnifier and Enrichment Pipeline to include the Detail Enhancer -split inventivity in adddetail and resharpen

    changlog 1.06 alfa V1

    Cleaned up vendor code to reduce namespace conflicts with the ComfyUI manager and custom nodes. Please note that the conflicts shown in the manager are pulled from a static list on the ComfyUI manager’s website and don’t necessarily reflect the actual code installed. I’m also unsure why this node is already listed in the manager’s custom node list, as I never registered it there.

    Finetuned Inventivity of TBG Magnific Magnifier In 1.0.5 versions, external custom nodes were required to inject noise into the sampling process. With the latest Rebuild Inventivity update, this is now integrated directly via the Inventivity slider. The Inventivity slider introduces dynamic noise behavior based on both the Inventivity and Denoise settings. It combines:

    • Per-step latent noise injection
    • Log-sigma manipulation at the model level
    • A poly-exponential curve applied to the sigma tail for controlled creative deviation

    The effect is non-linear, meaning low and high values produce very different results:

    • Low Inventivity values (0.1–0.5):
      Softens the output while enhancing subtle details. Useful for maintaining realism with light creative variation.
    • High Inventivity values (0.6–1.0+):
      Sharpens the image and enhances crisp, bold features. Great for stylized results. Results change a lot depending on denoise and cnets ... You can also plug in a Float node to push the Inventivity value above 1.0 if needed for more experimental outcomes.

    TBG Magnific Magnifier's color correction is now responsive to the denoise setting: at high denoise levels, color correction is minimal or disabled; at low denoise levels, full color correction is applied.

    TBG Magnific Magnifier now lets you switch between tiled and full-image refinement (full-image mode depends on your GPU memory and works fine for images up to around 3K resolution).

    TBG Magnific Magnifier increments the seed for the next pass to prevent pattern overlays caused by using the same noise in all samples (only affects images that are refined without upscaling).

    We’ve rebuilt the enrichment pipeline for TBG ETUR, which serves as the foundation for the inventiveness of the TBG Magnific Magnifier. This update introduces the Resharpener to improve image sharpness, a Creative Sigma Tail to boost creativity in later steps, and a remodified ETA value to inject noise into each sampling process. Activating this node will automatically switch the sampler to Euler Ancestral, or to RES2M if the RES4LYF node is installed. The upcoming Tile Upscale Plus will be available in two variations, one featuring a noise-reduction option that blurs input images before upscaling. Both versions upscale tiles in pixel space before sampling—by the specified factor—and then downsample after sampling to the chosen upscale resolution, resulting in finer detail and increased sampling time.

    We removed the split-sigma noise injection and latent-space noise injection methods, as both can be used only fot soft-merge sampling. However, they are incompatible with Tile Fusion and Neuro-Generative Tile Fusion so we removed it from the UI.

    changlog 1.05 alfa V3

    Resolved issues with membership recognition and ComputeUnit calculation Fixed guest user access issues Fixed CE node access for regular users Fixed an error in the TilerNode that occurred when the input image was smaller than the tile size Fixed EnhancementPipe — reduced dependency on external custom nodes by trimming features from DeamonTool and FinerDetails Fixed TBG Magnific Magnifier error related to missing installation of RES4LYF; temporarily replaced RES4LYF's ETA noise injection with DeamonTool

    changlog 1.05 alfa V2

    SDXL and negative conditioning support have been added to the TBG Magnific Magnifier.

    changlog 1.05 alfa

    Added the TBG Magnific Magnifier feature exclusively for Pro users.

    Fixed bug causing shadow lines on the last tile rows.

    Addressed and resolved all Groq-related bug reports.

    We removed the cropped tile approach on the last column and last row — these smaller tiles produced less accurate results due to missing fusion information. Now, all tiles maintain the full tile size for better consistency.

    changlog 1.04 alfa

    New Feature: FLUX KONTEXT Integration in CNETpipe The biggest highlight is the introduction of FLUX KONTEXT, offering a fully adaptive context pipeline that chains and stiches with ControlNetPipe Depth and Canny.

    Mask Attention Completely Overhauled Mask Attention has been rewritten from the ground up. It now works across both Pro and Community editions. A new border margin setting lets you fine-tune the mask's outer influence zone, and the segment sampling is now fully neuro-generative fusion capable, providing smoother, more organic blending between segments.

    Fusion Fixes & Tile Improvements We've patched several bugs in the Neuro Generative Fusion and Tile Fusion systems. Some users experienced glitches when tile sizes and border areas overlapped teh fusion area - that’s now resolved. Expect cleaner results and better alignment.

    Color Glitch Compensation Color artifacts caused by latent encode/decode are now handled much better. A new feature compensates for these VAE latent color glitches. It was generating faint lines along the tile joints when using high denoise settings.

    LLM Switching: Janus 1B and Janus 7B Now Supported You can now choose your preferred LLM directly from the node interface. Currently supported: Janus 1B and Janus/B — with more coming soon.

    Other Fixes and Tweaks Many small bugs and glitches reported by the community have been addressed — thank you for your feedback! This includes improvements to node stability, UI tweaks, and general robustness across the board.

    Give it a spin and let me know how it works for you. Your feedback always helps shape the next version so don’t hesitate to reach out!

    New Tile Cache We've updated the cache function for Soft Merge and Tile Fusion. You can now toggle the cache on or off at any time and choose between two modes:

    Full Cache Mode: Uses cached images for everything — including input tiles — allowing you to refine over previous refinements.

    Fusion-Only Cache Mode: Uses the original input tile but applies cached tiles only for surrounding areas during fusion.

    Due to the complex structure of Neuro Generative Tile Fusion (NGTF), the cache feature isn't yet fully effective for repairing individual tiles in NGTF. This is because overlapping areas from one tile don't directly affect the surrounding tiles without recalculating them too, especially when using higher denoise settings, resulting in imperfect blending.

    We're actively working to improve this behavior and aim to address it in the next release.
