+# 📔 PRODUCTION DIARY - SESSION: JAN 21, 2026 (UI FIXES)
+
+**Date:** 21.01.2026  
+**Session Time:** 02:42 CET  
+**Focus:** UI Asset Restoration & Transparency Fixes
+
+---
+
+## 🎯 **SESSION OBJECTIVES**
+1. Fix "checkerboard" issues in UI assets (Rusty Frame, Health Gauge, Start Button, Amnesia Mask).
+2. Restore proper transparency to allow game rendering (grass) to show through UI holes.
+3. Prepare new assets with "Green Screen" background for easier chroma keying (postponed due to quota).
+
+---
+
+## 🛠️ **WORK COMPLETED**
+
+### **1. UI ASSET RESTORATION (Manual + Script)**
+- **Problem:** AI-generated assets had baked-in grey/white checkerboard patterns instead of real transparency.
+- **Solution:** 
+    - Implemented `restore_and_fix_final.py` to process user-provided reference images.
+    - Used advanced color thresholding (chroma key logic) to strip white/grey pixels.
+    - Enforced strict resizing to game specifications:
+        * `okvir_zarjavel.png`: 800x250
+        * `merilec_zdravja.png`: 150x150
+        * `gumb_start.png`: 300x100
+        * `amnezija_maska.png`: 1920x1080
+- **Status:** All 4 core UI assets are now in `assets/slike/NOVE_SLIKE/UI/` with cleaner transparency.
+
+### **2. SCENE RENDERING ADJUSTMENTS**
+- Updated `GrassScene.js` to correctly layer these assets:
+    - **Depth 0:** Background (Grass)
+    - **Depth 10:** Characters (Kai, Ghosts)
+    - **Depth 100:** UI (Frame, Gauge, Mask)
+- Verified that "holes" in the rusty frame should now show the grass background.
+
+### **3. ASSET GENERATION QUOTA LIMIT**
+- Attempted to generate V5 assets with straight `#00FF00` green background for perfect keying.
+- **Blocker:** Hit Google Cloud Vision/Image quota limit (Resource Exhausted).
+- **Next Step:** Resume generation after 05:04 CET (quota reset).
+
+---
+
+## 📂 **FILE UPDATES**
+- `assets/slike/NOVE_SLIKE/UI/` - Updated with restored/fixed PNGs.
+- `restore_and_fix_final.py` - Created for batch processing updates.
+- `clean_backgrounds.py` - Updated with better algorithms.
+
+---
+
+## 📝 **NOTES FOR NEXT SESSION**
+- **Priority 1:** Wait for quota reset (Morning Jan 21).
+- **Priority 2:** Generate "Green Screen" versions of all UI elements if current transparency isn't perfect.
+- **Priority 3:** Final in-game verification of the "Amnesia Mask" effect.
