Quanta Shader is a fast shader pack for Java Edition, running on Iris and OptiFine. It adds soft sunlight, gentle bloom, real shadows, dynamic clouds and lively water. It needs nothing beyond the shader loader itself.
Shader loaders and versions
- Iris and OptiFine: Minecraft 1.19 to 26.3.
Effects and performance
The pack is tuned for modest hardware, and its listing promises high frame rates. That is the creator's aim, not a measured figure, so expect results to vary by machine.
- Soft shadows and gentle bloom
- Dynamic clouds and rich skies
- Reflective, lively water
Installation
- 1.Install Iris (on Fabric or NeoForge) or OptiFine.
- 2.Put the Quanta Shader .zip in the shaderpacks folder.
- 3.Open Video Settings, then Shader Packs, and select Quanta Shader.
New to shader loaders? The shader install guide covers the folder layout, and the troubleshooting guide helps if the pack does not appear. Bedrock cannot run Iris or OptiFine, so this pack is Java only.
A fork, with credit
The trade-off is plain. This is a light variation on an existing pack, not a new renderer, and the project links no source code.
Questions about Quanta Shader.
4 questions
How do I install Quanta Shader?
Install Iris or OptiFine first, then place the Quanta Shader .zip in your shaderpacks folder. Launch the game, open Video Settings, choose Shader Packs, and select Quanta Shader from the list. Iris runs on Fabric or NeoForge, while OptiFine works as its own mod.
Does Quanta Shader work with both Iris and OptiFine?
Yes. The pack is listed for both Iris and OptiFine, with a single file serving each loader, and that file asks for no other dependencies. Pick whichever loader you already use, and select the pack in its shader menu.
Is Quanta Shader the same as MakeUp Ultra Fast?
Not exactly. Quanta Shader is a fork of javiergcim's MakeUp Ultra Fast, renamed, cleaned up and slightly tweaked by Haider_x. The core lighting, shadows, water, sky and clouds come from the original, so the two look closely related.
Can I use Quanta Shader on Bedrock Edition?
No. Quanta Shader is a Java Edition shader pack that needs Iris or OptiFine, and both are Java mods that Bedrock cannot run. Bedrock uses a different format for visual packs, so this file will not load there.
