This ComfyUI workflow is designed for creators who want to leverage the massive creative potential and prompt adherence of Illustrious XL, while injecting the specific artistic textures of more specialized SDXL checkpoints.
The core philosophy is "Checkpoint Morphing": using a base model for "The Soul" (composition/concept) and a specialized model for "The Skin" (textures/line-work).
Key Features:
Dual-Pass Generation: Uses a high-denoise pass on Illustrious XL to establish the "creative bones" of the image.
Latent Refinement: A second KSampler pass with a lower denoise (optimized between 0.45 - 0.6) to "re-skin" the image using a second specialized checkpoint.
Artistic Preservation: Specifically tuned to maintain the silhouette and character likeness while transforming digital renders into traditional media styles like watercolor, ink-wash, or sketch.
Universal Compatibility: Works with any SDXL-based checkpoints, allowing for endless stylistic combinations.
How to Use:
Checkpoint 1: Load Illustrious XL (or your favorite creative base).
Checkpoint 2: Load a Specialized Model (e.g., Watercolor, Sketch, or Cinematic styles).
Prompting: Use your main prompt in the first stage. You can add style-specific trigger words in the second stage for better results.
Denoise Control: * 0.3 - 0.4: Subtle texture enhancement.
0.5 - 0.6: (Recommended) Balanced stylistic transformation.
0.7+: Major compositional shifts (high creativity, low fidelity to the original).
Requirements:
ComfyUI-Custom-Scripts (for better node management).
Impact Pack (optional, but recommended for face detailing).
🚀 Pro-Tip for Users:
If you find the composition shifting too much between passes, try lowering the denoise of the second KSampler. If the style isn't "bleeding" through enough, increase it slightly or add a style-specific LoRA to the second model.
