Vanilla Enhanced

🌿 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.
