Midnight1111_Abyss ComfyUI Workflow

ComfyUI Workflow //v01/18/25

Overview

Introducing Midnight1111_Abyss, a meticulously crafted ComfyUI pipeline designed to elevate your image generation process—particularly on Apple Silicon (M1, M2, M3) running macOS. Abyss seamlessly integrates the latest models for Illustrious SDXL, using samplers like res_multistep and kl_optimal, alongside specialized upscalers and Illustrious’ own ControlNets (Depth & Lineart). Nodes such as the IP Adapter refine background selection by default, though you can opt for a prompt + KSampler approach if that better suits your workflow.

:: Quick-Start Guide :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

1. Setup:

   • Install required models: Florence2 nodes, ControlNets (Depth & Lineart), and any optional upscalers or ADetailer models.

   • Place downloaded files in the corresponding folders (e.g., ComfyUI/models/).

2. Run Your Workflow:

   • Use the Fast Groups Bypasser (rgthree) to load the core pipeline.

   • Start with ✍ PROMPT, NEGATIVE PROMPTOIDS, Power Lora Loader (rgthree), Eff. Loader SDXL, Resolution Selector, ? Sampler Steps, & CFG nodes for foundational setup.

   • Add ControlNets (Depth or Lineart) to refine your results. Double-check that all required model files are correctly placed in their respective root folders before proceeding.

3. Refine & Save:

   • Utilize advanced masking, outpainting, and detailers to enhance specific features.

   • Preview changes before finalizing the output.

? Download Reminder: Illustrious’ ControlNets (Depth & Lineart) may require manual installation if not included in your ComfyUI preset.

3. ?️ Advanced Outpainting/Masking // Additional Padding Mask

• IP Adapter (Optional)

  • Facilitates background selection or changes prior to masking. Can be swapped for a standard prompt + KSampler approach if preferred.

    Tip: IP Adapter simplifies background manipulations but can be skipped for a leaner workflow.

• Advanced Masking:

  • Leverages specialized algorithms such as edge detection, region segmentation, and depth-based masking to isolate specific areas of your image for targeted edits.

  • Examples:

    • Edge Detection: Ideal for creating crisp outlines in illustrations.

    • Region Segmentation: Perfect for isolating characters or objects for detailed editing.

    • Depth-Based Masking: Enhances three-dimensionality by focusing on foreground or background elements.

• Outpainting:

  • Extends beyond the original canvas, enabling larger, more expansive scenes.

• Frame Masking:

  • Defines precise boundaries for controlled manipulations or expansions.

• Outpainting Frame:

  • Provides a visual guide to direct expansions, maintaining thematic cohesion.

4. ? Previews // Comparison and Masking

• Image Comparer Previewer

  • Enables side-by-side analysis of different workflow stages.

• Mask Comparer Previews

  • Displays masked vs. unmasked areas—crucial for verifying ControlNets or advanced masking techniques.

• Upscaler Previews

  • Offers detailed side-by-side comparisons of upscaled results.

• ADetailer Previews

  • Focuses on specialized detailer outputs (e.g., eyes, hair) for consistent enhancements.

5. ? Upscaling and Downscaling // Image Enhancements

• Upscale #1

  • Initial pass to significantly elevate resolution.

• Downscale

  • Optionally reduces resolution post-upscaling for specific sizes or aspect ratios.

• Upscale #2

  • Applies further refinement and detail enhancements for a polished final image.

  ? Explore upscaler models to suit your style.

Apple Silicon Note: Larger upscaler models may be GPU-intensive. If performance slows, adjust the Upscale Factors node for better compatibility with your hardware.

6. ?️ Detailers // Feature Enhancements

A robust set of tools for refining specific features—some may require separate model installations:

• Eye Detailer: Enhances iris clarity and reflection realism.

• Skin Detailer: Smooths textures while preserving natural pores.

• Hand Detailer: Improves anatomical accuracy of hands.

• Hair Detailer: Adds strands, shine, and realistic volume.

• Fashion Detailer: Refines clothing and fabric textures.

• Face Detailer: Harmonizes overall facial features.

• Breast Detailer: Improves chest-area anatomy for accurate portrayals.

7. ☑️ Model Compatibility // SDXL & SD1.5

• Flexible Model Loaders

  • Easily switch between SDXL, SD1.5, or other variants.

• Adaptive Settings

  • Fine-tune parameters to exploit each model’s strengths.

• Default Optimization

  • Midnight1111_Abyss ships with SDXL-optimized settings, delivering high-fidelity outputs on Apple Silicon.

Workflow Structure

• Grouping: Nodes are grouped by function (ControlNets, Upscalers, Detailers, IP Adapter, etc.). Entire sections can be toggled or bypassed with minimal risk to the main pipeline.

• Fast Groups Bypasser Integration: Quickly enable or disable node groups for testing, performance tuning, or skipping optional features like IP Adapter.

  • Back to Basics Node: Use this feature (by rgthree) to revert to core functionality without the additional features for a simpler workflow.

??‍? Apple Silicon Setup & Troubleshooting

A. Verify Your Environment

• Platform: Darwin (macOS on Apple Silicon)

• Python: 3.11.11

• PyTorch: 2.5.1

Check MPS availability:

python -c "import torch; print(torch.backends.mps.is_available())"

Should print True if MPS is enabled.

B. Enable MPS Fallback

If certain operations don’t fully support MPS, PyTorch can revert to CPU seamlessly:

1. Open your shell configuration file (e.g., ~/.zshrc) using nano:

   nano ~/.zshrc

2. Locate the section with other export lines, which configure environment variables. Add the following line next to them:

   export PYTORCH_ENABLE_MPS_FALLBACK=1

3. Save the changes by pressing CTRL + O, then press Enter to confirm. Exit nano by pressing CTRL + X.

4. Reload your shell configuration:

   source ~/.zshrc

Check:

echo $PYTORCH_ENABLE_MPS_FALLBACK

It should print 1.
