Recommended for preserving the base composition.- Global Only: Reuses the global positive prompt during refinement.- Global + Detail: Combines both prompts and reproduces the more creative behaviorOnly one selected conditioning text is encoded before one HR guider. The workflow does not add a second positive diffusion prediction or a DualCFG branch.### Refinement Profiles- Fidelity — default: Maximum structural and compositional stability.- Balanced: Moderate detail generation with controlled variation.- Creative: Stronger reinterpretation and denoise schedule.Profile denoise schedules:| Profile | 2K | 4K | 8K | 16K ||---|---:|---:|---:|---:|| Fidelity | 0.22 | 0.16 | 0.10 | 0.07 || Balanced | 0.26 | 0.20 | 0.14 | 0.09 || Creative | 0.32 | 0.26 | 0.18 | 0.12 |Fast Mode changes step counts only and does not silently modify the selected refinement profile.## Two Workflow Variants### Main Checkpoint VersionUses ComfyUI's standard checkpoint loader and supports compatible checkpoint-based models. The selected checkpoint supplies its own model, text encoder, and VAE components.### Krea2 VersionDesigned for Krea2-compatible diffusion models.Required components:- Model: Any compatible Krea2 model- Text encoder: <code>qwen3vl_4b</code>- Model type: <code>krea2</code>- VAE: <code>qwen_image_vae</code>The Main and Krea2 editions share the same interface, refinement profiles, HR conditioning modes, context-tile pipeline, output controls, and visual organization.## Resolution PipelineThe 4K, 8K, and native 16K paths use generative context-tile diffusion refinement. They are not simple raw interpolation passes.For systems with limited memory:- Enable Q3- Enable 16K Memory Saver- The workflow performs generative refinement through 8K and then uses one capped RTX VSR pass to reach 16K.For systems with sufficient RAM and VRAM:- Enable Q3- Disable 16K Memory Saver- The workflow performs native 16K context-tile diffusion refinement.Native 16K processing can require a very large amount of system RAM and VRAM. Hardware requirements vary by checkpoint, aspect ratio, tile settings, and model architecture.## Main Controls- T2I and I2I modes- Base width and height- Base seed- Control After Generate: fixed, randomize, increment, or decrement- Sampler and scheduler- Base, 2K, 4K, 8K, and 16K pass steps- HR Conditioning Mode- Refinement Profile- Fast Mode- Optional second and third quality stages- Tiled or regular base VAE decoding- Optional SageAttention acceleration- Optional RTX processing- 16K Memory Saver- Lossless PNG output- Configurable PNG compression- Embedded workflow and generation metadata## Output and MetadataThe final image is saved as lossless PNG with embedded workflow information.PNG compression changes encoding time and file size only. It does not reduce image quality.Generation metadata records the selected checkpoint or Krea2 UNET, HR conditioning mode, refinement profile, sampling configuration, pass settings, and resolution pipeline.A reduced front-panel preview is used to avoid sending the complete 8K or 16K image to the interface unnecessarily.## CompatibilityThis release uses the Classic/Legacy ComfyUI renderer.ComfyUI Nodes 2.0 beta is not required or recommended for this release.The workflow retains the external Legacy seed controller so Control After Generate remains available without converting the Master Settings subgraph to Nodes 2.0.## Required Custom Nodes- [Context-Anchored Tile Refine](<a target="_blank" rel="ugc" href="https://github.com/Blakeem/ComfyUI-ContextAnchoredTileRefine">https://github.com/Blakeem/ComfyUI-ContextAnchoredTileRefine</a>)- [ComfyUI-DaSiWa-Nodes](<a target="_blank" rel="ugc" href="https://github.com/darksidewalker/ComfyUI-DaSiWa-Nodes">https://github.com/darksidewalker/ComfyUI-DaSiWa-Nodes</a>)- [rgthree-comfy](<a target="_blank" rel="ugc" href="https://github.com/rgthree/rgthree-comfy">https://github.com/rgthree/rgthree-comfy</a>)- [ComfyUI-KJNodes](<a target="_blank" rel="ugc" href="https://github.com/kijai/ComfyUI-KJNodes">https://github.com/kijai/ComfyUI-KJNodes</a>)## Optional Acceleration- [SageAttention](<a target="_blank" rel="ugc" href="https://github.com/thu-ml/SageAttention">https://github.com/thu-ml/SageAttention</a>)SageAttention is required only when the SageAttention option is enabled in Master Settings. It is disabled by default because compatibility and performance gains depend on the GPU, PyTorch environment, model architecture, and attention implementation.## Recommended Starting SettingsFor maximum scene preservation:- HR Conditioning Mode: Detail Only- Refinement Profile: Fidelity- Tiled Base VAE Decode: Enable when normal VAE decoding exceeds available VRAM- 16K Memory Saver: Enable on systems that cannot process native 16K diffusion- SageAttention: Test per system before using it as a permanent defaultResults and resource requirements depend heavily on the selected checkpoint. No workflow can completely prevent semantic drift when denoise strength, prompt conditioning, or tile refinement settings are pushed beyond the selected model's capabilities.## License NoticeThe permissions selected on this Civitai resource apply to the original workflow JSON, layout, configuration, and release files created by Daruniawaesf.Third-party checkpoints, Krea2 models, custom nodes, SageAttention, and other dependencies remain subject to their respective licenses. -------------------------------------------------------------------------------------------------------------------------------<span style="background-color:rgb(26, 27, 30);color:rgb(250, 82, 82);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;font-size:16px">---------- <img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/175f905b-a103-4ca4-aae4-6e322dc08b9c/original=true/175f905b-a103-4ca4-aae4-6e322dc08b9c.jpeg" /> <img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/f8063c67-f9e8-4ca7-8115-3f552c2ec38e/original=true/f8063c67-f9e8-4ca7-8115-3f552c2ec38e.jpeg" /> <img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/8a56fce3-5f63-441e-ba85-9f8a7d9146db/original=true/8a56fce3-5f63-441e-ba85-9f8a7d9146db.jpeg" /> <img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/6903340e-a3f9-4cfd-a87d-03a171dfb8dd/original=true/6903340e-a3f9-4cfd-a87d-03a171dfb8dd.jpeg" /> <img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/41bcebd7-70d3-48fc-8eb1-7b1caf9eeb8b/original=true/41bcebd7-70d3-48fc-8eb1-7b1caf9eeb8b.jpeg" />
