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.
