RenderPearl

# Modern, lightweight shaders for Iris !(https://cdn.modrinth.com/data/BrRak9pu/images/9d2f33b85447099c25b6291b680608bc47c1f5e1.png) RenderPearl is an incredibly lightweight shader pack using the latest Iris features and optional extensions on various graphics drivers, aiming to deliver pleasant visuals with excellent performance on modern hardware. If you want to report a bug or give feedback/suggestions, the best way to do so is by opening an issue on the (https://github.com/Luracasmus/renderpearl/issues). I rely heavily on user feedback in bug fixing and design. <details> <summary>Trivia</summary> This project started as a continuation of "Luracasmus Shaders" (which is why you might have seen it called "LS RenderPearl"), but modern versions share little to no code with the original project. The question remains as to whether the same shader pack remains throughout, when all parts are replaced. The name "RenderPearl" is inspired by the Bedrock Edition (https://minecraft.fandom.com/wiki/RenderDragon) engine. </details> ## Features <details> <summary>LabPBR 1.3 compliance & material data </summary> "Yes" indicates support for per-texel data. | LabPBR 1.3 required component | From resource pack | Configurable nonstandard channels | Included/procedural | | ----------------------------- | ----------------------------------------- | --------------------------------- | ----------------------- | | Albedo | Yes | No | No | | Smoothness | Yes, or as linear or perceptual roughness | Yes | Yes | | f0/reflectance | No | | Constant | | Normal | Yes | No | Yes | | LabPBR 1.3 optional component | From resource pack | Included/procedural | | ----------------------------- | ------------------------------ | -------------------------------------- | | Hardcoded metal | No | No | | Porosity | No | No | | Subsurface scattering | No | Constant, only on translucent geometry | | Emmissiveness | No | Yes | | Ambient occlusion | Binary, per-block (from model) | Yes | | Height | No | No | </details> * Smooth, colored real-time shadows and volumetric light using distorted shadow mapping. * Colored block light with physically based reflections using a light list combined with vanilla lighting and average texture color. * Ray traced, per-hand hand light. * A wide range of highly optimized post-processing effects, including compute shader implementations of (https://gpuopen.com/fidelityfx-cas/), (https://www.iryoku.com/smaa/) 1x from (https://modrinth.com/shader/smaa-mc), automatic exposure and a variety of tone mapping operators. * Customizable waves and water opacity. * Built-in utility features such as light level visualization and a compass overlay. ## Mod & Resource Pack Compatibility Most built-in PBR information, including light colors, material normals and roughness, are almost entirely procedurally generated and should therefore work perfectly with most resource packs and mods. Integration with Distant Horizons and Voxy is supported on the latest Minecraft version, but experimental and very basic. Complete support is planned for a future update. Support for mods that modify the Iris shader pipeline, such as Chunks Fade In, is experimental and may have issues, such as the shader pack failing to compile. ## Requirements > If you have a decently modern non-macOS device it probably supports everything you need, but you might have to update your Iris and graphics drivers. * **Iris** with support for features: * `BLOCK_EMISSION_ATTRIBUTE` * `COMPUTE_SHADERS` * `CUSTOM_IMAGES` * `ENTITY_TRANSLUCENT` * `PER_BUFFER_BLENDING` * `SEPARATE_HARDWARE_SAMPLERS` * `SSBO` * **Graphics drivers** with support for **GLSL 4.60.8+**. * **Minecraft** of a version that is listed as supported by the RenderPearl release. The latest supported version is usually the most stable. <details> <summary>Driver Support</summary> | OS | Drivers | Support | | ------- | ----------------- | --------- | | Linux | Mesa RadeonSI | Perfect | | Linux | Nvidia |
