Vanilla Enhanced v1.17b — Changelog

Upgrade from v1.08

This update is a major internal rendering overhaul focused on modular shader architecture, improved visual fidelity, and better long-term maintainability. While the surface-level visuals may feel subtle, the underlying pipeline has been significantly reworked.

🚀 Overview

Version 1.17b introduces a separation of shader responsibilities (blocks, entities, terrain, sky), replacing the older monolithic approach used in v1.08. This enables more granular control, cleaner rendering logic, and future extensibility.

✨ New Features

🔹 Dedicated Shader Pipelines for Blocks & Entities

• Added:
• gbuffers_block.fsh / .vsh
• gbuffers_entities.fsh / .vsh

What this means:
- Blocks and entities are now processed through independent shader stages
- Enables:
- More precise lighting behavior per object type
- Cleaner separation of rendering logic
- Easier future feature additions (e.g. emissive entities, per-object effects)

❌ Removed

🔸 shaders.properties

• Fully removed from the shader pack

Why it matters:
- Configuration is now internalized into shader code
- Reduces dependency on external config parsing
- Improves consistency across shader loaders (OptiFine / Iris)

🔧 Changes & Improvements

🌌 Sky Rendering (gbuffers_skybasic.fsh)

• Refined atmospheric coloring
• Improved gradient transitions
• More stable brightness levels across time cycles

Result:
- More natural sky tones
- Reduced banding and visual artifacts

🌍 Terrain Rendering (gbuffers_terrain.fsh)

• Lighting calculations adjusted
• Improved shading consistency across blocks
• Better handling of indirect light

Result:
- More coherent world lighting
- Slightly improved depth perception
- Reduced harsh contrast in certain environments
