Iris · OptiFine

Photon Shader

A gameplay-focused shader with a fully revamped sky, detailed multi-layer clouds, and an immersive weather system that changes each day. The Ultra profile adds voxel-based colored lighting — a feature that requires Iris, because OptiFine can't support it. If you already run Iris, this is one of the few shaders designed to use its extra capabilities.

What Photon actually does

Photon is designed for gameplay rather than screenshots. The sky, lighting, and water are fully revamped. It includes detailed multi-layer clouds, an immersive weather system that changes the sky each day, and soft shadows with variable-size penumbras. The intent is not to look photorealistic — it's to make the world feel alive while you play in it, without breaking the aesthetic that makes Minecraft recognizable.

The Ultra profile enables voxel-based colored lighting, which requires Iris. OptiFine does not support this feature. That's the key distinction: most shaders that claim "colored lighting" are faking the effect with a tint applied to light sources. Photon's colored lighting is calculated as voxels that propagate through the world — a red torch genuinely tints nearby blocks red, not just its own glow.

The pack also includes temporal upscaling, disabled by default. On a low-end device that's struggling with frame rate, enabling it can be the difference between playable and not — at the cost of some sharpness in motion. The performance profiles (Low, Medium, High, Ultra) are the primary tuning knob; the Ultra profile is where the colored lighting feature activates.

How to install it

Photon is a shader pack, not a mod. It runs inside Iris or OptiFine. You drop it into shaderpacks, not mods.

  1. Install Iris (recommended) or OptiFine. Iris 1.5+ is required for Photon.
  2. Download the latest release from GitHub. Do not extract the ZIP.
  3. Place the .zip in .minecraft/shaderpacks.
  4. In-game: Options → Video Settings → Shader Packs. Select Photon. Start with Medium and step up to Ultra for the colored lighting.
Iris recommended. Photon's colored lighting feature is Iris-exclusive. On OptiFine, you lose this feature. Iris is also recommended for better performance and mod compatibility.

Frequently asked questions

Does Photon work on OptiFine?
Yes, on Minecraft 1.16.5 and above. However, colored lighting is Iris-exclusive and will not work on OptiFine.
Why is Photon laggy on my PC?
Photon's higher profiles are demanding. Reduce the profile to Medium or Low, disable volumetric effects, or use the temporal upscaling option (disabled by default) if you are on a low-end device.
Does Photon work with Distant Horizons?
Yes. Photon is compatible with Distant Horizons.
Why does colored lighting require Iris?
Voxel-based colored lighting uses features that Iris supports but OptiFine does not. The Photon author built it on Iris-specific capabilities, so on OptiFine you get the shader without the colored light feature.
What are the performance profiles?
Photon offers multiple profiles (Low, Medium, High, Ultra). Ultra enables the voxel-based colored lighting. Lower profiles are playable on mid-range GPUs, and the temporal upscaling option helps on lower-end systems.

Why this listing exists

Most resource sites either dump hundreds of unverified links with no context, or hide downloads behind fake countdown timers and redirect chains. This page follows a different approach: it shows the resource's real metadata, links to the creator's original page, and states clearly what we have and have not verified.
