A Vanilla shader resource pack implementing anti-aliasing and sharpening using the end-of-frame post effect added in Minecraft 26.3 Snapshot 3. The technique is a modified Enhanced Subpixel Morphological Antialiasing 1x followed by a modified FidelityFX Contrast Adaptive Sharpening 1.2.
The shaders require graphics drivers with support for GLSL 4.40. If you have a decently modern non-macOS device, it probably supports this, but you might have to update your graphics drivers. If support is missing, the pack will fail to load.
When Minecraft is using the Vulkan graphics API, the shaders may use lower precision math to improve performance. The behavior of this feature depends on your GPU and graphics drivers. Try switching graphics API if you're experiencing issues with the shaders, and please report them on the issue tracker.
Configuration
All configurable options are located in assets/grindstone/shaders/include/config.glsl inside the resource pack,
and can be modified with a text editor. The changes are applied when the pack is reloaded.
Older versions (named SMAA-MC)
Versions older than v2.0 are written as Iris shader packs rather than vanilla resource packs, and can be used with some Minecraft versions older than 26.3. They only implement SMAA 1x, with no sharpening, and re-implement vanilla-like rendering using code from Base-460C.
Requirements for versions older than v2.0
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:
COMPUTE_SHADERSCUSTOM_IMAGESENTITY_TRANSLUCENT
- Graphics drivers with support for GLSL 4.60.8+.
- Minecraft of a version that is listed as supported by the release.
- Updated and increased maximum supported pack format to 100.0
- Removed use of extension-provided trinary min/max-operations (fixes compilation failing with some NVIDIA graphics drivers ([#14](https://github.com/Luracasmus/grindstone/issues/14)))
[GitHub Release](https://github.com/Luracasmus/grindstone/releases/tag/v2.0.1%2B93.0-100.0)
- Improved color difference function to match redmean formula more accurately
- Updated and increased maximum supported pack format to 97.1
[GitHub Release](https://github.com/Luracasmus/grindstone/releases/tag/v2.0.0%2B93.0-97.1)
- Optimized SMAA edge detection
- Made SMAA local contrast adaptation factor in edge detection configurable, and lowered the default value
- Updated and increased maximum supported pack format to 94.0
- Minimum supported pack format is now 93.0
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v2.0.0-beta.1+93.0-94.0)
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v2.0.0-beta.0+91.0-92.0)
- This is a vanilla resource pack port of SMAA-MC (to be renamed to Grindstone)** using the new end-of-frame post effect added in Minecraft 26.3 Snapshot 3. A modified [FidelityFX Contrast Adaptive Sharpening 1.2](https://gpuopen.com/fidelityfx-cas/) pass has also been added to recover detail after anti-aliasing
See [the new description on GitHub](https://github.com/Luracasmus/smaa-mc/tree/vanilla)
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v2.0.0-beta.0%2B91.0-91.0)
- Updated light level conversion for compatibility with Iris 1.9.6+1.21.10. This breaks support for most older versions.
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v1.4.0)
- Changed the default Line Width to better match vanilla
6.0->2.5- Modified the border fog start distance algorithm to better match vanilla
- The Relative Border Fog Start option has been replaced by Border Fog Start Ratio
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v1.3.0)
- Merged the vanilla-like rendering implementation from [Base-460C](https://github.com/Luracasmus/Base-460C) to overwrite Iris' sometimes broken fallback shaders (Closes [#6](https://github.com/Luracasmus/smaa-mc/issues/6))
- This adds three new geometry-related shader pack options: Cloud Fog End, Relative Border Fog Start and Line Width. These properties would normally be dynamic and controlled by the game, but are unavailable in Iris' shader pack API and are therefore made available to the user for manual configuration
- Redesigned the shader pack options menu
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v1.2.0)
- Fixed incompatibility with some graphics drivers (Closes [#3](https://github.com/Luracasmus/smaa-mc/issues/3))
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v1.1.3)
- Fixed orientation-based shading being disabled (Closes [#1](https://github.com/Luracasmus/smaa-mc/issues/1))
- Enabled [
oldLighting](https://shaders.properties/current/reference/shadersproperties/features/#oldlighting)
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v1.1.2)
- Fixed an invalid color buffer format being specified, causing fallback to 8-bit RGBA
- 16-bit RGBA is now used
- Ensured rounding is consistent across OpenGL implementations
- This was missed while porting from HLSL to GLSL, since the HLSL
roundalways rounds midpoints towards even integers while the GLSLroundhas implementation-dependant behavior. GLSLroundEvenis now used instead
[GitHub Release](https://github.com/Luracasmus/smaa-mc/releases/tag/v1.1.1)
- Exchanged [Chebyshev distance](https://www.wikiwand.com/en/articles/Chebyshev_distance) for [redmean color difference](https://www.wikiwand.com/en/articles/Color_difference) in edge detection, to more closely match human perception
- Micro-optimized blending weight calculation
- Converted LUTs to raw textures to enable smaller color formats on the GPU
