Lemony Shaders pour Minecraft 1.20.1, 1.21.1

LemonyShaders

A lightweight shader pack that makes reflective surfaces actually feel reflective. Water, metal, ice, glass, honey, and slime each get their own screen-space reflections and material response, layered on a clean, close-to-vanilla lighting base — no heavy performance cost from volumetrics or path tracing.

Features

• Screen-space reflections on water, metal, ice, glass, honey, and

slime — each with its own roughness and reflectivity for a distinct look

• PBR-style specular highlights on metal blocks (iron, gold, copper)

using a Cook-Torrance BRDF

• Two water modes — flat textured normals, or fully procedural

animated wave ripples (no texture needed)

• Swaying leaves with per-block randomized motion
• Day/night light color shift
• Soft shadows with PCF filtering

Good for: players who want realistic-looking water, glass, and metal without switching to a full graphics overhaul — light on performance, easy to run alongside resource packs.
