    About

    PSX Shader NB is a fork of ckosmic’s Minecraft PSX Shader, aiming to recreate the look and feel of PlayStation 1 graphics. It removes the original shader’s vertex-bouncing effect while moving and adds continuously updating dynamic light from held torches, lanterns, and other light sources in either hand. Held-light illumination uses linear distance falloff and affects terrain, entities, water, the player’s hand, and basic geometry. The shader works with both OptiFine and Iris.

    Written from Modrinth . How we write it

    In-game changes

    Changes how the game looks: 15 shader programs, for the End. Draws its own water, sky, clouds and weather.

    Security

    No harmful code found

    We checked what is inside its files.

    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 · The latest file checked, last on 23 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do. Fixed rules tell what is harmful.
      2 latest files: the newest file for each Minecraft version and loader. The answer above is about the one 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. See each file in Releases
    • 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

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images and code history and found none.

    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.
