    💡 Usage Tips

    Getting Started with Presets

    With JavaScript Extension (Recommended):

    1. Install the JS extension (see Installation)
    2. Select any preset from dropdown
    3. Watch all fields update automatically! ✨
    4. Generate immediately - no manual adjustment needed

    Without JavaScript Extension:

    • Presets still work internally
    • UI fields won't update visually, but preset values ARE being used
    • Check console output to see applied values
    • Consider installing JS extension for better UX

    Advanced Custom Formulas

    Write any mathematical curve you can imagine! The formula uses t as variable (0 to 1).

    Popular Formulas:

    # Sine wave (3 oscillations)
"sin(t * 3 * 3.14159)"

# Ease-in-out cubic
"3*t**2 - 2*t**3"

# Double peak
"exp(-((t-0.3)**2)/0.05) + exp(-((t-0.7)**2)/0.05)"

# Exponential rise with plateau
"1 - exp(-t*5)"

# Polynomial curve
"3*t**2 - 2*t**3"

# Sawtooth wave
"(t*4) % 1"

    Curve Blending Strategies:

    • Blend linear with sine_wave for subtle rhythm
    • Blend ease_out with bell_curve for complex transitions
    • Use low blend amounts (0.1-0.3) for subtle variations

    Adaptive Keyframes:

    • Turn ON for custom formulas with rapid changes
    • Turn OFF for simple curves (saves computation)
    • Most useful with sine waves, bounce, and custom formulas

    CSV Export:

    • Save successful curves for reuse
    • Share curves with the community
    • Document your workflows

    Understanding Curve Direction

    The curve type controls the SHAPE, your strength values control the DIRECTION:

    Example with ease_in (slow start, fast end):

    • start=1.0, end=0.0 → Stays at 1.0 for a while, then drops quickly to 0.0
    • start=0.0, end=1.0 → Stays at 0.0 for a while, then rises quickly to 1.0

    Example with exponential (dramatic growth):

    • start=0.2, end=1.5 → Slowly starts at 0.2, then dramatically shoots up to 1.5
    • start=1.5, end=0.2 → Stays high at 1.5, then drops dramatically to 0.2

    Pro Tip: Use the graph preview to verify your curve looks correct before generating!

    Mask Painting Tips

    • Paint each region as a separate mask - don't worry about opacity
    • Use full opacity - the strength settings control the effect
    • Allow small overlaps - use blend_mode=max to handle them
    • Test one region at a time - easier to dial in individual strengths

    Regional Prompting Best Practices

    Base Prompt:

    • Use for universal quality tags: "masterpiece, high quality, detailed"
    • Avoid specific objects/subjects

    Regional Prompts:

    • Be specific about what's in that region
    • Include style/lighting/atmosphere for that area
    • Can include negative concepts if needed

    Strength Values:

    • Start at 1.0 for all regions
    • Increase if a region isn't responding (1.2-1.5)
    • Decrease if a region is overpowering others (0.6-0.8)

    Prompt Interpolation Tips

    Interpolation Steps:

    • 3-5 steps: Faster, more distinct regions
    • 8-12 steps: Smooth, natural transitions
    • 15-20 steps: Ultra-smooth, subtle gradients

    Transition Modes:

    • linear: Quick experiments, testing
    • smooth: Best for natural transitions (recommended)
    • ease_in_out: Dramatic effects, artistic shots

    Gradient Direction:

    • Use auto first - it usually picks correctly
    • Override if transition looks wrong
    • radial great for center → edge effects

    Symmetry Tool Tips

    When to Use:

    • Portraits (faces, eyes, facial features)
    • Architecture (buildings, windows, facades)
    • Nature (butterflies, flowers, leaves)
    • Any symmetrical subject

    Blend Modes:

    • max: Default, works for most cases
    • add: When you want overlap to be stronger
    • average: For subtle, softer symmetry
    • replace: For hard-edge symmetrical masks

    Pro Tip:

    • Use radial_4way for mandala-like patterns
    • Combine with invert_mirrored for creative negative space effects

    🛠 Troubleshooting

    Issue: ControlNet not working at all / no effect

    • ⚠️ Solution: Check your Advanced ControlNet node settings!
      • Set strength to 1.00
      • Set start_percent to 0.000
      • Set end_percent to 1.000
      • These settings must be correct for the scheduler to work!

    Issue: Curve going in wrong direction

    • Solution: The curve shape is correct, but swap your start_strength and end_strength values
    • Remember: Curve types control SHAPE, not direction

    Issue: Graph not showing

    • Solution: Make sure matplotlib is installed: pip install matplotlib
    • Set show_graph=false if you don't need it

    Issue: Custom formula not working

    • Solution:
      • Check syntax - use t as the variable
      • Make sure formula evaluates to numbers between 0-1 (auto-normalized)
      • Avoid forbidden operations (import, exec, eval)
      • Test with simple formulas first: t**2, sin(t*3.14)

    Issue: Preset UI fields not updating

    • Solution: Make sure you restarted ComfyUI after installation
      • Hard refresh browser (Ctrl+Shift+F5 / Cmd+Shift+R)
      • Check browser console (F12) - you should see ✅ Node patched successfully!
      • If you don't see that message, the extension may not have loaded
      • Verify /web/advanced_curved_scheduler.js exists in your node folder
    • Alternative: Presets still work without UI updates - values are applied internally
      • Check browser console (F12) for ✅ Preset applied successfully! message when changing presets
      • The correct values ARE being used even if UI doesn't update visually

    Issue: Masks not affecting output

    • Solution:
      • Check that masks are actually painted (not empty)
      • Verify mask is connected to correct input
      • Try increasing strength values
      • Verify Advanced ControlNet base strength is 1.0

    Issue: Effect too weak everywhere

    • Solution:
      • Check Advanced ControlNet strength setting (should be 1.0)
      • Increase start_strength and end_strength values in scheduler
      • Increase base_strength in Multi-Mask Strength Combiner

    Issue: Effect too strong everywhere

    • Solution:
      • Decrease start_strength and end_strength values
      • Decrease individual mask strengths in Multi-Mask Combiner
      • Check that Advanced ControlNet strength isn't multiplying your values

    Issue: Regional prompts bleeding into each other

    • Solution:
      • Make sure masks don't overlap (or use interpolation node for intentional blending)
      • Use more specific prompts
      • Adjust region strength values

    Issue: Symmetry creating unexpected results

    • Solution:
      • Check that your mask doesn't already cover both sides
      • Try different blend modes
      • Reduce blend_strength for subtler effect

    Issue: Interpolation not visible

    • Solution:
      • Increase interpolation_steps (try 10-15)
      • Use transition_mode=smooth for more obvious gradients
      • Check that masks are positioned to allow transition zones

    Issue: CSV export not working

    • Solution:
      • Check file permissions in ComfyUI/output/curves directory
      • Verify save_curve is set to True
      • Check console for error messages

    📋 Requirements

    • ComfyUI
    • ComfyUI-Advanced-ControlNet (required)
    • Python packages: matplotlib, pillow, numpy, torch, scipy
