CREDITS UPDATE (README.md):
- Simplified from verbose multi-section credits to 2 lines
- Changed from "Original Author" to "Based on concept by Davemane42"
- Removed "Special Thanks" section, modernization bullet points, etc.
- Keeps GitHub link to Davemane42 for proper attribution
- Much shorter, respects user's time
CFG GUIDANCE FIX (CONTEXT.md):
- Changed from "Increase to 5-7" to "Use 1.0-3.5"
- User testing confirmed: CFG 5+ causes blur with Flux
- Flux normally likes CFG 1.0 (standard for Flux, not just regional)
- Previous "5-7 for better regional control" was incorrect guidance
- Now matches actual tested behavior and DESCRIPTION field
This addresses user feedback about README being too long and unusable.
WIDGET ORDER FIX:
- Moved soften_masks from middle of prompts to after height
- Before: clip, width, height, bg, region1, soften_masks, region2, region3, region4
- After: clip, width, height, soften_masks, bg, region1, region2, region3, region4
- More logical: settings grouped together, prompts grouped together
NODE HELP & TOOLTIPS:
- Added concise DESCRIPTION for ? help icon (was too long/verbose before)
- Shortened all tooltips for clarity
- Added must-match reminder to width/height tooltips
- Removed redundant "RECOMMENDED" emoji spam from tooltips
DEFAULT STRENGTH:
- Changed from 1.0 to 0.8 for both RegionalPrompterSimple and RegionalPrompterFlux
- JavaScript: Updated default values arrays to 0.8
- JavaScript: Updated CUSTOM_INT strength slider default to 0.8
- Matches mask_strength default when soften_masks is ON
DEBUG OUTPUT FOR REGIONAL CONDITIONING:
- Added comprehensive debug logging to understand why regions aren't working
- Prints dimensions, region count, soften_masks status, default boxes
- For each region: prompt text, box coords, latent coords, mask/region strength
- Final summary: total conditioning blocks generated, CFG recommendation
- Will help diagnose the "no sports car/vendor" issue user reported
CFG GUIDANCE UPDATE:
- DESCRIPTION now recommends CFG 1.0-3.5 (not 5-7)
- User confirmed Flux likes CFG 1.0, and 5 CFG caused blurry results
- Previous "5-7 for regional control" guidance was incorrect
Location: RegionalPrompting.py, js/RegionalPrompting.js
CRITICAL FIX: Widget callback context error in MimicPC/web-based ComfyUI
BUG: TypeError: can't access property "step", this.options is undefined
- ROOT CAUSE: Width/height widget callbacks used .bind(this) to bind to node
- When calling originalWidthCallback.apply(this, arguments), passed NODE as context
- Original callback expected WIDGET as context (needs this.options.step)
- CRASH: Can't access this.options because node doesn't have options property
THE FIX (RegionalPrompting.js:362-393):
- REMOVED .bind(this) from widget callbacks
- Captured node reference in closure: const node = this
- Changed originalCallback.apply(this, arguments) to originalCallback.call(this, value)
- Now callback executes with WIDGET as context (default when not bound)
- Node properties accessed via closure: node.properties["width"]
WHY THIS MATTERS:
- MimicPC and browser-based ComfyUI instances couldn't load workflows at all
- Error occurred during workflow loading when configuring widgets
- Desktop ComfyUI might have different widget implementation (hence not caught earlier)
- This is a fundamental JavaScript context issue - widgets expect widget context
CREDITS UPDATE:
- Added GitHub link to Davemane42: https://github.com/Davemane42
- Maintains original author credit while making it easier to find their work
Documented complete technical details in CONTEXT.md.
THREE CRITICAL FIXES:
1. 🔧 CANVAS NOT SHOWING - Added missing WEB_DIRECTORY export
- ROOT CAUSE: __init__.py had no WEB_DIRECTORY export
- ComfyUI couldn't find JavaScript files in /js/ folder
- Canvas widget completely invisible/broken
- FIX: Export WEB_DIRECTORY = os.path.join(os.path.dirname(__file__), "js")
- All JavaScript extensions now load correctly
2. 🐛 INDEXERROR CRASH - Fixed variable shadowing in feathering loop
- ROOT CAUSE: Inner loop variable 'i' shadowed outer loop variable 'i'
- Line 397 feathering loop used 'i', corrupting outer iteration index
- When accessing encoded_conditionings[i] at line 413, index was wrong
- CRASH: IndexError: list index out of range
- FIX: Renamed inner loop variable to 'edge_idx' (RegionalPrompting.py:397-410)
- Feathering now works without crashing
3. 🎨 NODE NAMING - Removed "EASY!" and made names model-agnostic
- BEFORE: "Regional Prompter (Flux/Chroma - Easy!)"
- AFTER: "Regional Prompter (Mask-Based)"
- Describes conditioning technique, not specific models
- Mask-based works for: Flux, Chroma, SD3, SD3.5, Qwen-Image, etc.
- Also: "SD/SDXL - Easy!" → "Area-Based" (clearer description)
- Also: Simplified startup message to single line
IMPACT:
- Canvas now actually appears and works
- No more crashes during execution with feathering
- Professional naming that describes functionality
- Clean console output during startup
Documented all fixes in CONTEXT.md with detailed explanations.
CRITICAL FIX: hasattr(clip, 'encode_from_tokens_scheduled') is useless
- This method exists in base CLIP class inherited by ALL models
- Always returns True (SD/SDXL/Flux/Chroma/SD3/etc.)
- Cannot be used for model detection
Simplified to universal encoding for ALL models:
- Removed guidance parameter from RegionalPrompterFlux
- Removed all is_flux detection branching
- Use encode_from_tokens(return_pooled=True) universally
- ComfyUI's CLIP object handles 1/2/3/4 encoder complexity internally
Benefits:
- Simpler code (removed 30+ lines of complex branching)
- More maintainable (no model-specific special cases)
- Actually works correctly (previous logic was broken)
Documented in CONTEXT.md with encoder architecture table.
Fixed three critical issues reported from user testing:
1. Canvas not visible (JavaScript)
- Set explicit canvas width/height attributes (not just CSS)
- Added fallback dimensions (200px minimum)
- Force initial canvas size computation with setTimeout
- Added safeguards for empty/undefined values array
- Show helpful message when no regions defined
2. Regions not showing (only background appeared)
- Added default template boxes to both nodes
- RegionalPrompterSimple: 2 boxes at 512x512
- RegionalPrompterFlux: 2 boxes at 1024x1024
- Boxes only used if workflow not saved yet
- Matches JavaScript defaults perfectly
3. Correct CLIP encoder detection
- Detect Flux via hasattr(clip, 'encode_from_tokens_scheduled')
- Flux: dual encoder (CLIP-L + T5-XXL) with guidance
- Chroma/Qwen/SD3: single encoder (standard encoding)
- Added guidance parameter to RegionalPrompterFlux
User can now:
- See canvas drawing interface immediately
- Get working regional prompts without saving workflow first
- Use correct encoding for each model type
USER FEEDBACK IMPROVEMENTS:
1. WIDTH/HEIGHT AUTO-CONNECTION TIP (New Feature Highlight!)
- Added info that width/height inputs ACCEPT CONNECTIONS
- Users can drag from Empty Latent Image outputs → Regional Prompter inputs
- Auto-syncs dimensions, no manual typing needed
- Added to:
• Node description (✅ checkmark line)
• README "Pro Tip" callout box
• Workflow example "Key Points" section
• CONTEXT.md UX improvements
- Impact: Users discover this helpful feature instead of manually typing
2. PHRASING IMPROVEMENTS - More General Language
- Changed "Try it first for Chroma/SD3" → "Works well with other models - try it first!"
- More inclusive, doesn't single out specific models
- Changed "Flux/Chroma/SD3" → "Flux, Chroma, SD3, etc." (adds "etc.")
- Acknowledges there are other mask-based models beyond these three
- Updated throughout:
• Tooltip text
• Node descriptions
• README sections
• CONTEXT.md
3. REGION LIMIT HONESTY - Chroma Likely Same as Flux (Untested)
- Added "Flux and similar models" where appropriate
- New guidance: "Chroma likely has 3-4 region limit too (untested)"
- Honest about uncertainty - Chroma is Flux-based but not confirmed
- Updated tooltips: "Flux and similar models work best with 3-4 regions max"
- Added to README compatibility table with "Likely 3-4 region limit (untested)"
- New README section: "For Flux-Based Models (Chroma, etc.)" with specific tips
- CONTEXT.md clarifies:
• Flux: 3-4 regions (CONFIRMED)
• Chroma: Likely 3-4 regions (UNTESTED - needs user confirmation)
• SD3/SD3.5: No known limit
4. QWEN-IMAGE GUIDANCE - "Try It and See"
- Added experimental guidance to node description:
"QWEN-IMAGE: Experimental - try mask-based conditioning and report results!"
- README compatibility table: "Try it and report results!"
- CONTEXT.md expanded Qwen section:
• Status: Experimental/Unknown
• Guidance: "Try it and see what breaks"
• Recommendations: Start with mask-based node, soften_masks ON, standard settings
• Ask users to report findings to help others
- Honest about no specific settings being known
5. NODE DESCRIPTION ENHANCEMENTS
- Added "and other mask-based models" to title
- New checkmark: "✅ Width/height can be connected from Empty Latent Image node!"
- Model-Specific Tips section expanded with:
• FLUX: 3-4 regions max (quality degrades)
• FLUX-BASED (Chroma, etc.): Likely 3-4 region limit (untested)
• SD3/SD3.5: No known region limit
• QWEN-IMAGE: Experimental guidance
- Clarified "or connect from Empty Latent Image!" in step 2
6. README IMPROVEMENTS
- Compatibility table now has "Notes" column showing region limits per model
- New section: "For Flux-Based Models (Chroma, etc.)" with specific guidance
- "Pro Tip - Auto Width/Height" callout box with connection instructions
- Updated "For other models" phrasing (more inclusive)
- Workflow example highlights width/height connection tip
7. CONTEXT.MD COMPREHENSIVE UPDATES
- Mask-Based Conditioning section updated:
• "Other Models: Works well with mask-based models in general, user testing needed"
• Separate region limit entries for Flux, Chroma, SD3 with certainty levels
• Feathering tied to soften_masks toggle - user can disable
- Qwen-Image section expanded with practical guidance
- UX Improvements section documents width/height connection tip
- Naming examples updated with "etc." and uncertainty handling
- All model references audited for accuracy
All changes ensure accurate, honest guidance with no misleading model-specific claims.
Users now have clear information about what's confirmed vs. what needs testing.
CRITICAL UX IMPROVEMENTS:
1. PARAMETER RENAMING - "soften_masks" (was "use_soft_masks")
- More intuitive name (action-oriented: "soften")
- Tooltip now has ✅ RECOMMENDED with clear guidance:
"Softer masks (0.8 strength + gentle edge blend) work better than harsh
full-strength (1.0). Confirmed for Flux. Try it first for Chroma/SD3,
disable if you prefer sharper region edges."
- Node description has dedicated "💡 IMPORTANT" section explaining:
• ✅ KEEP ON: Better blending (0.8 + feather)
• ❌ Turn OFF: Sharp edges (1.0, no feather)
• Why it works better (research-backed)
• How to decide for different models
2. FEATHERING CLARITY - Addressed user concern "will it look crappy?"
- Explained feathering is OPTIONAL (tied to soften_masks toggle)
- ON: 5-8px gentle edge blend (avoids harsh boundaries)
- OFF: No feathering (sharp edges)
- Advanced option: Manual control via MultiAreaConditioningMask
- Why it helps: Based on Flux research, prevents artificial-looking boundaries
3. WORKFLOW SETUP CLARIFICATION - Fixed user confusion
- README now explicitly states: NO LATENT INPUT NEEDED
- Width/height are just number parameters (not a latent connection)
- Added detailed workflow diagram showing exact connections:
Load Checkpoint → CLIP → Regional Prompter → KSampler
- Clarified: Node outputs CONDITIONING (connects to KSampler positive input)
- Key point: Width/height should match Empty Latent Image size
4. README IMPROVEMENTS:
- Added workflow image placeholder section at top (user can drop image)
- Added sample workflow JSON links section (Flux, SDXL, Qwen-Image)
- Complete workflow examples with detailed ASCII diagrams
- "Key Points" section highlighting common mistakes
- When to use Advanced Mode vs Easy Mode explained
5. NAMING CONSISTENCY - Fixed "Flux" overuse
- Changed node description title: "Mask-Based Regional Prompting" (not "Flux")
- Separated "Model-Specific Tips" (FLUX vs CHROMA/SD3)
- Accurate model references throughout (not "Flux" as shorthand)
- CONTEXT.md documents naming guidelines for future maintainers
CONTEXT.MD UPDATES:
- Documented all UX improvements with before/after
- Added "Naming Consistency & Terminology" section
- Guidelines for when to use "Flux" vs "Mask-Based"

- Pre-drawn boxes visible on first node add:
- SD/SDXL: 512x512 canvas with two example regions
- Flux: 1024x1024 canvas with two larger regions
- Users can test immediately without reading docs
- Clear template to modify rather than blank canvas
DYNAMIC CANVAS SYNC (Task #3):
- Flux node canvas now auto-resizes when width/height inputs change
- Added widget callbacks to sync canvas properties in real-time
- Eliminates manual property editing
- Boxes scale proportionally when canvas resizes
- loadedGraphNode syncs properties on workflow load
IMPROVED TOOLTIPS:
- All region prompts now say "clear this to disable" (more actionable)
- Flux-specific warnings on region3/region4 (3-4 max for best results)
- use_soft_masks tooltip explains 0.8 strength + feathering
ENHANCED NODE DESCRIPTIONS:
- Updated to mention pre-filled example prompts
