RedHat Shaders is a semi-realistic, fantasy-leaning shader pack for Java, built by mlgimposter as an edit of Chocapic13. It runs on Iris and OptiFine, needs no other mods, and sits at a medium performance tier. Colors shift with the time of day, so the pack reads as realistic and fantasy at once.
Shader loaders and versions
- Iris and OptiFine: Minecraft 1.7.2 to 26.3.
Effects and lighting
Lighting is the draw. Godrays come in 3D, with a 2D option for weaker machines, alongside shadows and underwater light absorption. Reflections are included, and surfaces bounce some light back for a plastic sheen that can be tuned. Foliage and hanging items such as lanterns sway, and the pack also covers PBR support, auto-exposure, stars, fog, clouds and a round sun and moon.
- Lens flare
- Depth of field with chromatic aberration
- Grain and tilt shift
- Waving hand and waving camera
- Custom skies from texture packs, plus vanilla clouds
Performance and settings
mlgimposter pitches RedHat at medium-range PCs, not low-end ones. The stated needs are a GPU with OpenGL 3.2 and 1 GB of VRAM, a 1 GHz CPU and 2 GB of RAM allocated. Intel GPUs need lowered settings, though 40 to 50 FPS is possible with an Intel UHD chip. Nearly every effect can be adjusted from the shader settings menu.
Installation
- 1.Install Iris or OptiFine for your Java setup.
- 2.Get the .zip from the CurseForge page and place it in the shaderpacks folder.

Questions about RedHat Shaders.
3 questions
Is RedHat Shaders good for low-end PCs?
The creator recommends it for medium-range PCs rather than low-end ones. With lowered settings, an Intel UHD GPU can reach roughly 40 to 50 FPS. The stated minimum is a GPU with OpenGL 3.2 and 1 GB of VRAM, plus 2 GB of RAM allocated.
Does RedHat Shaders work with Iris and OptiFine?
Yes, the pack has builds for both Iris and OptiFine. The creator does warn that Iris may have some issues with it, so if you hit problems on Iris, check the settings and driver situation before assuming the pack is broken.
Does RedHat Shaders work on Bedrock?
No. It is a Java shader pack, and the loaders it relies on, Iris and OptiFine, are Java mods that Bedrock cannot run. Bedrock uses a different shader format, so this pack will not load there.
