About
Alpha Piscium is a realistic Minecraft shaderpack that enhances the game’s lighting, atmosphere, clouds, shadows, and reflective surfaces. Its real-time global illumination uses ReSTIR-based screen-space techniques with ReBLUR denoising, producing indirect and specular lighting while managing noise and temporal artifacts. Atmospheric scattering uses an Unreal Engine sky-atmosphere rendering technique and epipolar sampling, while Nubis-based volumetric clouds add changing cloud formations and cloud-filled skies. Adaptive shadows, rectilinear texture warping, and water rendering with surface reflections, refraction, and underwater volumetric effects round out the visual treatment. The pack also offers configurable built-in metalness overrides and material data for known blocks, and supports PBR resource packs for nighttime lighting.

Security
No harmful code found
We checked what is inside its files, without opening them in the game.
Why we show this: a shader cannot run programs, but its file can hide one. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.1 latest file, for a recent version. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks.

- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
Privacy
Sends nothing
A shader has no code that can connect to the internet, so it cannot send anything about you.
AI
AI was used for its code and text
The author declares AI code and text on Modrinth.
We looked for AI tools in its texts, files and images and found none.
We have not read its code history yet.
Why we show this: some players and servers avoid projects made with AI. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Declares AI code, text.
