Shrimple
by Null
A simple, lightweight shader focused on colored block light and clean visuals. Shrimple is designed for Iris and prioritizes performance while adding meaningful visual improvements.
What Shrimple looks like in-game
Shrimple ships 6 headline effects. Each preview below is a hand-drawn illustration of what that effect does to a Minecraft scene, not a screenshot of the pack itself - the screenshot at the top of the page is the real thing.
Colored lighting
Torches burn orange, lava burns red, sea lanterns burn blue, and the room takes on that colour.
Shadows
The sun and moon drag a real shadow behind every block, tree and mob as the day moves.
Bloom
Bright sources bleed light into the pixels around them, so glowstone and lava actually glow.
Enhanced water
Water gets depth, moving ripples and clarity instead of a flat blue plane.
Waving vegetation
Every plant in the world picks up the same breeze, so fields move as one.
Custom sky
A redrawn sky with its own day-to-night gradient, sun, moon and star field.

What you need to run Shrimple
An overview of Shrimple
Shrimple is a performance Minecraft shader pack by Null, aimed at a clear visual lift that still runs fast. It rebuilds the game's lighting engine to deliver efficient shadows and lighting tuned to spare frames, transforming flat vanilla blocks into a world with real light and shadow. It carries a light performance cost and supports Minecraft 1.16.5 - 1.21.
The look is defined by coloured light from torches, lava, and glowstone, dynamic shadows cast by the sun and moon, bloom that makes bright sources glow, and reworked water with depth, ripples, and clarity. Together these effects reshape every scene, from the way morning light rakes across terrain to how water and glass catch reflections at dusk.
Shrimple suits players on modest or older hardware who still want shaders. Players highlight its excellent colored lighting and very lightweight as standout qualities. It runs through Iris on Minecraft Java, and its low-tier demands mean it pairs best with the hardware described in the requirements below.
What Shrimple changes
Unlike a texture pack, Shrimple does not repaint blocks - it replaces how Minecraft lights and renders the scene. Here is what it adds to your game:
- Colored lighting: it adds coloured light from torches, lava, and glowstone.
- Shadows: it adds dynamic shadows cast by the sun and moon.
- Bloom: it adds bloom that makes bright sources glow.
- Enhanced water: it adds reworked water with depth, ripples, and clarity.
- Waving vegetation: it adds vegetation that sways naturally in the breeze.
- Custom sky: it adds a redrawn sky with a richer day-night cycle.
- Overall direction: the result is a clear visual lift that still runs fast, applied consistently across the whole world.

How to install Shrimple
- 1Install Fabric (or Quilt) for your Minecraft version, then add the Iris Shaders mod - Shrimple is an Iris-targeted shader and needs it to run.
- 2Download the Shrimple .zip from the official source linked above. Keep it zipped.
- 3Launch Minecraft with the Iris/Fabric profile, open Options, then Video Settings, then Shader Packs.
- 4Click "Open Shader Pack Folder" and drop the Shrimple .zip into the folder that opens.
- 5Select Shrimple from the list and click Apply. The shader compiles and loads after a short pause.
Running Shrimple smoothly
Shrimple sits in the low-impact tier, meaning a light performance cost over vanilla Minecraft. Most systems, including laptops and integrated graphics, hold a smooth frame rate.
As a baseline it lists GTX 750 / RX 550 with 1 GB of VRAM and 2 GB of system RAM. That keeps the bar low, so even older dedicated cards and many integrated chips can run it once OptiFine or Iris is installed.
Shrimple officially supports Minecraft 1.16.5 - 1.21. Running it on a version outside that range may cause visual glitches until the author updates it, so match your client to a supported release.
Because the cost is modest, you can usually raise render distance or pair Shrimple with an HD texture pack without dropping below a smooth frame rate.
