• Implemented safer block ID validation (range checking)
• Added additional safety checks for invalid block IDs
• Improved wind animation filtering to prevent edge cases

Technical Changes

• Separated block exclusion logic from inclusion logic
• Added water, flowing water, ice, chests, and glass to blocked blocks list
• Enhanced vertex shader safety with multi-level ID validation
• Better handling of edge cases in block ID detection

Version 1.0 - Initial Release

Core Features

Dynamic Sky System

• Smooth day/night cycle transitions with custom color gradients

🌿 Vanilla Enhanced Shader v1.00 - Full Release Changelog

---

---

• Small things are changed,
• Contrast changed.
• Weather changed.

🌿 Vanilla Enhanced Shader v0.97 - Changelog

---

---

🔆 Sun / Moon Direction Fix:

• Now properly uses sunPosition and moonPosition uniforms when available.
• If unavailable, a reliable fallback calculation is applied.
• Sun movement now follows the correct east-to-west trajectory using cos / sin.

---

🔥 Torch PBR Fix:

• Torch light is now fully omnidirectional (radiates in all directions).
• Added rim lighting for torches, enhancing glow realism.
• Softer specular highlights (power reduced from 64 → 16).
• Introduced a minimum ambient value (0.2) for consistent visibility.

---

👁️ View Direction Correction:

• viewDir now correctly computed as: normalize(cameraPosition - worldPos)
• All calculations are now consistent in world space.

---

💎 Reflection Calculation Fix:

• Proper reflection vector using: reflect(-lightDirection, normal)
• Accurate specular highlights based on: dot(viewDir, reflectionDir)
• Ensures reflections respond correctly to camera angle.

---

✅ Overall Impact:

• Sunlight and moonlight now illuminate from the correct directions.
• Torches provide consistent, realistic lighting from all angles.
• Specular reflections behave properly based on camera perspective.
• No more north-locked lighting artifacts — lighting directions now feel natural.
