Bliss is a fantasy-styled shader pack for Minecraft Java Edition that runs on the Iris and OptiFine pipelines. Built as an edit of Chocapic13's shaders, it favors scene variation and deep customization over a single fixed look, and the project positions itself in the medium performance tier. Bliss is client-side only and does not support Bedrock Edition.

What Bliss changes in-game

Bliss reworks lighting, water, and weather so the same world reads differently across times of day and biomes. Its standout feature is colored block lighting, so torches, lava, and glowstone tint the surfaces around them instead of just brightening them. The settings menu is broad, which lets you push the look from soft and atmospheric toward sharper and more reflective.

  • Colored block lighting that tints nearby surfaces from torches, lava, and other light sources.
  • LabPBR support, including specular reflections, subsurface scattering, emissiveness, and parallax occlusion mapping with compatible texture packs.
  • A daily weather system that varies skies, including overcast and rainy conditions.
  • Distinct atmosphere per environment, from the Nether and caves to oceans and the End.
  • A deep settings menu for tuning the look and the performance cost.

How to install Bliss with Iris or OptiFine

Bliss needs a shader loader. Install Iris (usually with Sodium) or OptiFine first, then add the shader pack.

  1. 1.Install Iris or OptiFine for your Minecraft version and launch the game once on that profile.
  2. 2.Download the Bliss shader pack zip from its Modrinth project page. Keep it zipped.
  3. 3.Open Options, then Video Settings, then Shaders (Shader Packs on OptiFine) and click the folder button to open your shaderpacks directory.
  4. 4.Move the Bliss zip into the shaderpacks folder.
  5. 5.Return to the shaders menu and select Bliss to apply it.

Compatibility and Distant Horizons support

Bliss includes Distant Horizons support, so the pack can shade the level-of-detail terrain that Distant Horizons draws beyond the vanilla render distance. It also reads LabPBR resource packs for reflections and material detail. Because Bliss is a Java shader pack, it does not work on Bedrock Edition.

Performance and settings

The project describes Bliss as a well-performing pack, and its categories place it in the medium tier rather than the lightest or the most demanding. Effects like reflections, volumetric lighting, and Distant Horizons shading raise the cost, so lowering or disabling them in the shader settings is the main lever if your frame rate drops. Pairing Iris with Sodium generally gives the smoothest result.

Questions about this entry.

  • How do I install Bliss Shaders?

    Install a shader loader first: either Iris, usually alongside Sodium, or OptiFine for your Minecraft version. Download the Bliss zip from its Modrinth page and leave it zipped. In game, open Video Settings, then Shaders, click the folder button to open the shaderpacks directory, drop the zip in, and select Bliss from the list to apply it.

  • Does Bliss work with Iris and OptiFine?

    Yes. Bliss is published for both the Iris and OptiFine pipelines, so you can run it on either. Many players pair Iris with Sodium for better frame rates, but OptiFine remains a supported option if that is the setup you already use.

  • Does Bliss Shaders support Distant Horizons?

    Yes. Bliss ships with Distant Horizons support, so it can shade the level-of-detail terrain Distant Horizons renders past the normal view distance. For this to work cleanly, keep Distant Horizons, Iris, and Bliss on compatible versions, since the shaded far terrain depends on the loader and the pack agreeing.

  • Is Bliss good for low-end PCs?

    Bliss sits in the medium performance tier, so it is heavier than minimal vanilla-like packs but lighter than the most demanding realistic ones. On weaker hardware you can lower or turn off costly effects such as reflections and volumetric lighting in the shader settings, and running Iris with Sodium helps recover frames.

  • Which Minecraft versions does Bliss support?

    Shader compatibility follows the loader rather than a single fixed game version, so Bliss runs through whichever recent Iris or OptiFine build you install. Check the files list on the Bliss Modrinth page for the version you play and match it to your Iris or OptiFine install.
