ProjectLUMA
by DeDelner
The spiritual successor to KUDA Shaders. ProjectLUMA features refined volumetric lighting, natural color grading, and a clean visual style.
The ProjectLUMA look, effect by effect
ProjectLUMA ships 8 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.
Volumetric lighting
Light becomes visible in the air itself: shafts hang between trees and pour through cave mouths.
Shadows
The sun and moon drag a real shadow behind every block, tree and mob as the day moves.
Reflections
Water and polished blocks mirror the world standing above them.
Bloom
Bright sources bleed light into the pixels around them, so glowstone and lava actually glow.
Custom sky
A redrawn sky with its own day-to-night gradient, sun, moon and star field.
Waving plants
Grass, crops and leaves bend and rebound in the wind instead of standing frozen.
Color grading
A film-style grade is laid over the whole frame, shifting shadows and highlights together.
ProjectLUMA in short
ProjectLUMA is a realistic Minecraft shader pack by DeDelner, aimed at grounded, true-to-life visuals. It rebuilds the game's lighting engine to deliver naturalistic sunlight, soft shadows, and believable colour, transforming flat vanilla blocks into a world with real light and shadow. It carries a moderate performance cost and supports Minecraft 1.12.2 - 1.20.4.
The look is defined by volumetric light shafts streaming through gaps and trees, dynamic shadows cast by the sun and moon, godrays that pour through the canopy and over hilltops, and reflections on water and polished blocks. Together these effects reshape every scene, from the way morning light rakes across terrain to how water and glass catch reflections at dusk.
ProjectLUMA suits players who want Minecraft to look real without losing its identity. Players highlight its clean, refined visuals and natural color grading as standout qualities. It runs through OptiFine on Minecraft Java, and its medium-tier demands mean it pairs best with the hardware described in the requirements below.

ProjectLUMA against vanilla Minecraft
Unlike a texture pack, ProjectLUMA does not repaint blocks - it replaces how Minecraft lights and renders the scene. Here is what it adds to your game:
- Volumetric lighting: it adds volumetric light shafts streaming through gaps and trees.
- Shadows: it adds dynamic shadows cast by the sun and moon.
- Godrays: it adds godrays that pour through the canopy and over hilltops.
- Reflections: it adds reflections on water and polished blocks.
- Bloom: it adds bloom that makes bright sources glow.
- Custom sky: it adds a redrawn sky with a richer day-night cycle.
- Overall direction: the result is grounded, true-to-life visuals, applied consistently across the whole world.

- 3Launch Minecraft with the OptiFine or Iris profile, then open Options, Video Settings, Shaders (Shader Packs on Iris).
- 4Click "Shaders Folder" / "Open Shader Pack Folder" and move the downloaded ProjectLUMA .zip into it.
- 5Back in the menu, click ProjectLUMA to select it, then Apply or Done. Give it a moment to compile on first load.
Performance and requirements
ProjectLUMA sits in the medium-impact tier, meaning a moderate performance cost over vanilla Minecraft. A dedicated mid-range GPU keeps frame rates comfortable at normal render distances.
As a baseline it lists GTX 960 / RX 470 with 2 GB of VRAM and 4 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.
ProjectLUMA officially supports Minecraft 1.12.2 - 1.20.4. 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 ProjectLUMA with an HD texture pack without dropping below a smooth frame rate.
ProjectLUMA: common questions
What do I need to run ProjectLUMA?
You need a shader loader - either OptiFine or Iris - for Minecraft. Hardware-wise, ProjectLUMA lists GTX 960 / RX 470 with 2 GB of VRAM as a baseline.
Is ProjectLUMA good for low-end PCs?
ProjectLUMA has a medium performance impact. It is comfortable on a dedicated mid-range GPU but may need lower settings on integrated graphics.
Which Minecraft versions does ProjectLUMA support?
ProjectLUMA officially supports Minecraft 1.12.2 - 1.20.4. For the smoothest experience, run a Minecraft client within that range alongside a matching version of OptiFine or Iris.
What are the downsides of ProjectLUMA?
The trade-offs worth knowing before you install are OptiFine only and development can be slow. For most users the visual payoff outweighs these, but they are the points players raise most often.
How do I install ProjectLUMA?
Install OptiFine or Iris, drop the ProjectLUMA .zip into your shaderpacks folder, then enable it under Video Settings, Shaders. Full steps are above.
