⚡ Illustrious Workflow as of version 18f
🛠️ Purpose & Design Philosophy
This workflow is a high-fidelity environment built for Illustrious XL. 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 SDXL 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.
All-in-One Logic: The workflow handles generation, detailing, and upscaling in one continuous pass.
If you're needing all the bells and whistles: Try checking out ComfyUI Image Workflows by Legendaer here on CivitAI.
🚀 Key Features & 2026 Logic
Global Model Patching (RescaleCFG): Includes a pre-configured RescaleCFG patch (Multiplier: 0.7) applied globally. This acts as "HDR Insurance," preventing the "deep-fried" or over-saturated look common in high-CFG Illustrious runs.
Detail Daemon Sampler: Integrated to enhance structural depth. In this version, it is tuned to start at 0.4 to preserve the core Illustrious character proportions while sharpening hair and eye details.
Hybrid Upscale Strategy: * Group Bypass Switch: Easily toggle between a RTX VSR path for flat anime styles and an Upscale-Model path for 2.5D/highly detailed renders.
Ultimate SD Upscale: Re-draws the upscaled canvas at a 0.2 to 0.35 denoise to lock in fine textures.
Power LoRA Loader: Manage multiple Illustrious-specific LoRAs without messy wiring.
Triple Detailer Groups: 3-stage targeted refinement for faces, hands, and clothing using standard detection models.
CivitAI Meta-Sync: Images are saved with full metadata (Model, LoRAs, Sampler info) for automatic site parsing.
⚠️ Disclaimer & Compatibility
Install at Your Own Risk: Custom nodes can break your environment. I am not responsible for troubleshooting your specific installation.
ComfyUI Portable: Built and tested on the Portable 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.

Description
Release Notes: Illustrious Workflow v18d & v18d-RTX (both are on the same downloadable file).
This update focuses on refined sampling math and hardware-accelerated post-processing. To accommodate different hardware setups, this release includes two separate versions of the workflow.
Workflow Versions
v18d: The standard high-performance version compatible with all GPU architectures.
v18d-RTX: Optimized specifically for Nvidia RTX GPUs, utilizing Tensor-core accelerated upscaling and cleaning nodes for maximum clarity.
Major Changes & New Features
1. Sampling Evolution: Lying Sigma & Detail Daemon
Added: Lying Sigma Sampler (from the Detail Daemon project).
Removed: RescaleCFG.
Why? The Lying Sigma Sampler provides more granular control over the noise floor during the sampling process. This allows for deeper "2.5D" skin textures and material details (satin, leather, lace) without the over-saturation or "crunchiness" sometimes introduced by RescaleCFG.
2. Nvidia RTX Integration (v18d-RTX Only)
For users with Nvidia RTX hardware, we have replaced the standard model-based upscalers with dedicated hardware nodes:
RTX Video Super Resolution: Provides a cleaner, artifact-free base for USDU.
RTX Denoise & Deblur: Used at the final stage to polish the output. These are highly effective at sharpening hair and accessories while removing the "micro-noise" often left behind by high-scale upscaling.
3. Impact Wildcard Processor
Status: Added (Disconnected by default).
Usage: For those who use wildcard libraries, simply connect the output of this node to your positive prompt text boxes. It’s included as a "lean" optional utility to keep the workflow organized for power users.
4. On-Canvas Documentation
New Markdown Notes have been added directly to the workflow canvas. These provide step-by-step explanations of the RTX node settings and the new sampling logic, ensuring you don't have to leave ComfyUI to understand the new setup.
Installation Notes
Requirements: Ensure you have the
Nvidia_RTX_Nodes_ComfyUI,ComfyUI-PIX_Nvidia_RTX_Deblur_Denoise, andComfyUI-Detail-Daemoncustom nodes installed via the ComfyUI Manager.Hardware: The RTX version requires an Nvidia RTX GPU and non-ancient drivers (probably) to function, I use the 591.74 Studio driver. If you are on an older GTX card or non-Nvidia hardware, please use the standard v18d file.
