LiteCraft Shader

LiteCraft Shaders v1.0 is a small Minecraft Java shader pack (about 30 KB) made for Iris on Fabric, with a clear focus on weak PCs. The README says it was tuned for cards like a GT 730 / 2 GB. It is a forward-shaded pack: one shadow pass and one post-process pass, not a heavy deferred pipeline like Complementary or SEUS.

The zip name is v1.0, but the files inside do not all agree on the version. README.txt calls it v2.0, shaders.properties still says v1.6, and the changelog covers v1.3 through v2.0. In practice this archive is the current LiteCraft build, not a bare first draft.

What it does

It replaces vanilla lighting with a lighter custom look:

• Real-time sun and moon shadows, with optional 4-tap soft shadows
• A shadow floor, so daytime shade is not pitch black
• Warm sunrise/sunset tints and cooler moonlight
• Sky-colored ambient light instead of gray fill light
• Custom sun and moon discs, including real moon phases
• Lit vanilla clouds with shaded undersides (best with Fancy clouds)
• Distance fog that is not tied to render distance, so lowering chunks for FPS does not flood the sky with fog
• Waving grass, leaves, crops, and vines
• Water waves plus a cheap sun glint
• Custom raindrops with a slight glass shine, blue-white color, and wind drift
• Optional volumetric sunbeams (god rays), also used underwater with a simple caustic shimmer
• Tiny sparkles on snow in direct sun
• Reinhard tonemap, saturation, contrast, exposure, and a light vignette
• Reads the game lightmap, so Fullbright mods and the vanilla Brightness slider still affect the image

Block IDs are mapped in block.properties: plants/crops, leaves, water, and snow.

Settings and profiles

The in-game menu is grouped into Shadows, Sky/Sun/Clouds, Light Brightness, Waving & Water, Rays/Caustics/Snow, and Color Grading. English and Persian (en_us, fa_ir) language files are included.

How it is built

Inside shaders/ there are standard Iris/OptiFine programs:

• gbuffers_terrain, water, clouds, skybasic, skytextured, weather, entities, textured, textured_lit, basic
• shadow and final
• Shared code in lib/common.glsl, light.glsl, postfx.glsl, wave.glsl

Shaders are written for GLSL 1.20, which matches old GPUs.

Install

Leave the zip closed and put it in:

%appdata%\.minecraft\shaderpacks

Then: Options → Video Settings → Shader Packs → LiteCraft-Shaders. The README recommends the Fast profile, Fancy clouds, Sodium, and 3–4 GB of allocated RAM. If FPS is still low: Potato profile, render distance 6–8, Fast graphics, fewer entities.

Limits

This is not a high-end cinematic pack. There is no PBR, no screen-space reflections, no dense volumetric clouds or fog, and entity/block-entity shadows are off. Pretty mode exists, but the pack’s real purpose is a nicer vanilla look on weak hardware. The README also notes it was made for ahmadihaha8.
