Only supports Iris 1.7.1-1.7.5 ## New Features * Dynamic Color Grading: * Uses data from multiple frames to automatically adjust exposure, color balance and black point before/during tone mapping * Replaces Automatic Exposure * Held dynamic light sources * [PBR Neutral](https://github.com/KhronosGroup/ToneMapping/blob/main/PBR_Neutral/README.md) and [SBDT](https://github.com/bevyengine/bevy/blob/main/crates/bevy_core_pipeline/src/tonemapping/tonemapping_shared.wgsl) tonemap operator support * Specular Map support (a bit more properly this time!) * Small utility features (can be found in Misc): * [Light Level Visualization](https://modrinth.com/resourcepack/light-levels) * Simple compass overlay ### Experimental * Colored Block Light: * Colored light with glossy BRDF-based reflections, with brightness based on Vanilla lighting * Uses both SSBOs and Custom Images * Varies significantly in performance and quality * [SMAA](https://www.iryoku.com/smaa/) - Enhanced Subpixel Morphological Antialiasing: * An alternative to the existing FXAA that preserves more sharpness and clarity * Currently experimental in RenderPearl due to some issues with it's implementation ## Improvements * Switched from Phong to BRDF lighting * Improved shadow quality and performance using [a fast gaussian blur approximation](https://web.archive.org/web/20230210095515/http://the-witness.net/news/2013/09/shadow-mapping-summary-part-1/): * Can be toggled for solid and translucent shadows, or disabled to use the Linear and Off (Nearest) blur options * Improved the skylight color calculation * Used faster texture sampling functions where possible * Switched to [RCA Sharpening](https://github.com/GPUOpen-Effects/FidelityFX-FSR2?tab=readme-ov-file#robust-contrast-adaptive-sharpening-rcas) * Made moon phase affect moonlight color * Lava is now recognized as a fluid and has waves! * Switched to a more accurate sRGB <-> Linear conversion * Renamed Translucent Shadows to Subsurface Scattering, and improved its quality and performance: * There is now another list in `block.properties` containing blocks affected by SSS (which can only be of cutout type) ## Removed Features * Variable Penumbra Shadows (because it didn't work with the new shadow blur) * Reinhard-Jodie Tonemap Curve option * Emissive Flowers and Fungi options (as they were incompatible with the new SSS) * Cloud lighting calculation (which didn't even work) ## Other Changes * Reverted default profile back to High * Lowered default Volumetric Light amount * Enabled RCA Sharpening by default * Disabled [shadow interval snapping](https://shaders.properties/reference/constants/shadowintervalsize/) ## Fixed Issues * Dropped items render incorrectly * Enchantment glint animation is frozen (reported by [drakray](https://www.planetminecraft.com/member/drakray/)) * Entities are treated as water in the shadow pass * The `BLOCK_EMISSION_ATTRIBUTE` Iris feature is used but not marked as required * Some post-processing effects run in the wrong order
