Requires Iris 1.8+ ## New Features * Implicit normals and normal map support 🎉 * **Implicit normals currently cause compile failures on some AMD GPUs! Please enable RP Normal Maps if the shaders fail to load** Using [Meteor](https://www.planetminecraft.com/texture-pack/lmx/)  Using purely auto-generated normals and smoothness  ## Improvements * Further major improvements to index-based lighting * Lights are now de-duplicated based on position, concurrently with shadows, volumetric light and sky rendering * Lighting Level Of Detail is now based on range, significantly improving performance with almost no visible effect on quality * Added LOD Falloff and Lava LOD Bias options * The light index is no longer recreated every frame * The rate at which this happens is now controlled by the new Index Rate option * Tiles/work groups now only allocate memory for part of the global index, which works well because of highly effective culling * The ratio between global and local index size is controlled by the new LDS Ratio option  * The shader pack options screen has been completely redesigned  * Dynamic Color Grading has been rewritten entirely * The implementation is now multi-threaded and uses significantly more samples to gather accurate color data from the screen * Implicit smoothness calculations are now relative to average surface brightness * This should make smoothness more consistent between materials * The FXAA implementation has been improved * Fixed blending in the wrong color space * More uniforms are now combined * Precision of color and data buffers has been increased by using better packing ## Fixed Issues * Block light is incorrect on translucent geometry * Indexed light sources sometimes flicker (reported by [Farmer_Markus](https://www.planetminecraft.com/member/farmer_markus/)) * Lava & water fog color is incorrect * Shadow mapping is enabled in the nether * Opaque hand and handheld items render at the wrong depth * Volumetric Light is inaccurate and causes light leaks
