a custom retro CRT shader pack for Minecraft (Iris compatible). It shrinks the screen resolution to a pixelated 500x700 format, restricts the color palette for a 90s aesthetic. Made by UraniumTr, it leans cursed / fantasy and ships atmosphere and path tracing. Expect it to run comfortably from potato-tier hardware upward, on Minecraft 1.21 – 26.2 via Iris or OptiFine. Licensed MIT, so the download is mirrored right here on MineSpecs — no ads, no redirects.
