What CoffeeShaders works with.
| Platform | Java Edition |

CoffeeShaders is a lightweight cartoon and vanilla-like shader pack for Java, running on Iris and OptiFine. It is a visual edit of GlacierShaders for players who like that clean look but want something warmer. It works on the player's own install only, so nothing needs adding to a multiplayer host.
Shader loaders and versions
- Iris: Minecraft 1.20 to 26.2. Some builds for 1.20 to 1.21.5 require Iris Shaders.
- OptiFine: Minecraft 1.20 to 26.2.
What changes on screen
The pack keeps almost the same visuals as GlacierShaders. The main difference is tone. Water gets a rich coffee-coloured tint, and a few effects are adjusted so the scene feels softer and cozier.
- Smooth shadows that stay clean rather than harsh.
- A subtle bloom that adds a warm glow.
- Adjustable settings in the shader menu for personal control.
- Minimal post-processing and no heavy visual effects.
Performance and trade-offs
Modrinth tags the pack as potato, low and medium, and the creator describes it as optimized for performance without reducing FPS. That suits modest hardware. The cost is a narrow feature set, since it is billed as a mid-quality pack with minimal post-processing. If you already use GlacierShaders, the gain is mostly the water colour and the warmer mood.
Installing CoffeeShaders
- 1.Install Iris on Fabric or NeoForge, or install OptiFine.
- 2.Place the pack's .zip file in the shaderpacks folder.
If the pack does not appear or the screen turns black, the shader troubleshooting guide covers the usual causes. Bedrock cannot run Iris or OptiFine, so this pack is Java only.

Questions about CoffeeShaders.
4 questions
How do I install CoffeeShaders?
Install Iris or OptiFine first. With Iris, some builds for 1.20 to 1.21.5 also need the Iris Shaders mod, so check which one you downloaded.
Does CoffeeShaders work with Iris and OptiFine?
Yes. The pack ships builds for both loaders, covering Minecraft 1.20 to 26.2. Both are Java tools, so Bedrock players cannot use it. The pack applies on the player's own install and is not something a multiplayer host runs.
Is CoffeeShaders good for low-end PCs?
It is aimed that way. Modrinth tags it potato, low and medium, and the creator says it uses minimal post-processing with no heavy effects. Actual frame rates still depend on your hardware, your render distance and the other mods you run.
How is CoffeeShaders different from GlacierShaders?
CoffeeShaders keeps almost the same visuals but adds a coffee-coloured water tint and a few tweaks for a warmer, softer feel. Its performance goals match GlacierShaders.
