TrueLightFX v5.1.2 - Compatibility & Color Hotfix

Fixes for Compatibility of Older Game Versions

• Fixed a shader compilation crash (endCol undeclared) on older Iris and OptiFine versions by converting relative include paths to absolute paths and ensuring End color variables are declared globally.
• Fixed a pipeline crash (Non [a-z0-9/._-] character in path) on older Iris versions by converting uppercase Prismarine block IDs to lowercase in block.properties.
• Restored original End dimension color parameters (END_R, END_G, END_B, END_I) in settings.glsl to bring back the intended blue-violet look instead of red.

TrueLightFX v5.1.1 - Hotfix Update

Features & Improvements

• Set the default performance preset to Medium on first startup
• Aligned default shader settings with the Medium preset profile

Fixes

• Fixed glowing plants, flowers, and ores (spore blossoms, glow berries, glow lichens, etc.) not emitting light on Low, Medium, High, and Ultra presets
• Fixed a bug where the shaderpack would display as "Custom" instead of "Medium" on first startup

TrueLightFX v5.1 - Compatibility & Bugfix Update

This release brings full compatibility with Minecraft 1.20 through 1.21.2, addresses a critical rendering issue that made the player model look transparent, and optimizes performance presets.

Features & Improvements

• 1.21+ Compatibility: Fully updated block mappings for modern Minecraft versions (1.20 - 1.21.2).
• New Animated Blocks: Added waving animations to Cherry Leaves, Pale Oak Leaves, Dry Grass, Hanging Moss, and Moss Carpets.
• Realistic Waving: Adjusted waving speed and algorithms to be much more natural and realistic.
• Updated Emissives: Added support for Copper Bulbs, Trial Spawners, Vaults, Crafters, Creaking Hearts, and Resin Blocks.

Performance

• Shadow Map Optimization: Optimized shadow map resolutions across performance profiles to improve FPS.
• Low-End Optimization: Disabled generated normals, specular, and emissive calculations on the Minimum profile for a significant FPS boost.
• Vertex Math: Streamlined waving calculations to reduce GPU overhead.

Bug Fixes

• Player Transparency: Fixed the bug where the player model and held items would appear transparent/see-through in third-person view on land and near water.
• Falling Speed Glitch: Fixed waving speed accelerating when the player moves vertically or falls.
• Copper Bulb Typo: Fixed a block properties typo that prevented oxidized copper bulbs from glowing correctly.
• Refraction Artifacts: Fixed incorrect refraction masking affecting entity outlines.

TrueLightFX V4.4

This update focuses on improving lighting calculations, shader stability, and environmental animations. Several internal shader files were optimized to make the rendering more consistent and reliable.

Improvements

Sun Angle Calculation

The shader now uses sunAngle instead of worldTime for calculating the sun position.
This results in smoother day and night transitions and more accurate shadow fading during sunrise and sunset.

Cloud Rendering

Cloud rendering has been adjusted to better match the sky lighting and exposure.
This improves overall visual consistency in different weather and lighting conditions.

Waving Animations

The waving system for vegetation has been improved.
Grass, plants, and other foliage now move more smoothly and naturally.

Lighting Adjustments

Improvements were made to the deferred lighting pipeline to create more consistent brightness and better environmental lighting.

Fixes

Fixed advanced materials compatibility issues.

Fixed shadow fade timing issues.

Fixed minor problems in the hand rendering shader.

Fixed lighting inconsistencies caused by previous time calculations.

Cleaned up shader configuration settings.

Internal Changes

The following shader files were updated:

deferred1.glsl

shadow.glsl

gbuffers_hand.glsl

clouds.glsl

waving.glsl

settings.glsl

shaders.properties

These changes mainly improve rendering accuracy and shader stability.

Major fix

-Fixed the Advanced Materials bug now fully (sometimes in the V4.2 in FirstPerson your Item Texture could be buggy)

-Fixed stuttering bugs

CHANGELOG FOR TLFX V4.2

-Fixed ´´TLFX Material and surface - normals and 3d depth effect bugs´´

-Fixed ´´Rain Reflections ´´
