🛠️ Purpose & Design Philosophy
This workflow is a high-fidelity environment built for Illustrious. It prioritizes stability and professional texture over generation speed. It follows an "all-in-one" philosophy: configure your prompts, hit queue, and let the workflow handle the multi-stage refinement from start to finish.
Not for Speed: This is a heavy-duty refinement tool. If you want 2-second previews, use a basic workflow.
Personal Use: Built for my specific production needs. It is shared as-is for those who want a "set-and-forget" pipeline for Illustrious. Adjust the settings and models to fit your needs. The defaults on v19+ will be what I used for the sample images.
All-in-One Logic: The workflow handles generation, detailing, and upscaling in one continuous pass.

⚠️ Disclaimer & Compatibility
Install at Your Own Risk: Custom nodes can break your environment. I am not responsible for troubleshooting your specific installation.
ComfyUI: Built and tested on the non-app version. Desktop app users may face additional hurdles.
The "Your Version" Factor: Your node versions and environment are 99.9% likely to differ from mine.
Nodes 2.0: I do not recommend using Nodes 2.0. It creates unpredictable UI behavior; I will not provide support for issues involving this feature.
🤝 Support & Boundaries
I have not and never will monetize my workflow. CivitAI is the only platform I am maintaining this workflow on. If you find a version of my workflow posted and/or monetized anywhere and use it, then whoever posted it is responsible for providing you any support. This is the main reason why I don't monetize this: I don't want to be or feel obligated to provide support.
No DMs: DMs are disabled due to repeat spam. Please check the Discussions tab below; most questions have already been answered.
Modifications: You are free to hack this workflow apart. However, you are responsible for fixing it if it breaks.
Custom Requests: I do not make private workflows. If you need a custom solution, post a Bounty on CivitAI. There are many talented creators ready to help you for a fee.
Description
Update Notes: v18g
This update focuses on expanding the high-resolution pipeline for those who want to push their outputs to the absolute limit. We are re-introducing a refined multi-stage upscaling logic that I’ve been testing to solve the "muddiness" often found in massive upscales.
New Feature: Secondary USDU Refinement Pipeline
In v18g, I have added an optional secondary set of groups designed to "double-down" on detail and texture. This is a complex chain that includes:
Image Downscaling: To reset the pixel grid.
Pre-USDU2 Upscale: To prepare the canvas.
CFG Zero Star USDU2 & Ultimate SD Upscale 2: For the final detail injection.
⚠️ The "Double-Edged Sword" Warning
This new pipeline is powerful but can be temperamental. While it excels at creating incredible skin textures and cinematic lighting, it can struggle with high-frequency micro-patterns.
Best For: Portraits, skin-heavy shots, and dramatic low-key lighting.
Avoid For: Fine lace, intricate embroidery, or extremely dense mechanical greebles.
Note: If your image starts looking "over-processed" or you lose the crispness of fine threads, simply Bypass the 2nd USDU groups.
Recommended Settings (TL;DR)
To get the best out of the dual-pass system, the goal is "High Precision, Low Impact" on the second pass:
Pass 1: Use your standard settings to build the structure.
Pass 2: Increase the Step Count but Lower the Denoise (suggested range: 0.20–0.35 depending on your sampler/scheduler combo).
The Logic: This allows the sampler more time to refine the image without having enough "permission" to radically change or blur your existing details.
Other Changes
Legacy Support: The simple Image-to-Image option introduced in v18f remains fully integrated.
Workflow Optimization: General cleanup to accommodate the new node groups without sacrificing the overall speed of the Illustrious base.
