About Iris Shaders

Iris Shaders is the modern shader loader for Minecraft Fabric, with over 40 million downloads from players seeking beautiful graphics without sacrificing the performance gains from Sodium. When you host a server supporting Iris-equipped clients, you're enabling players to experience your world with stunning visual enhancements.

Why Support Iris on Your Server?

Players using Iris can experience your server's builds with dramatic lighting, realistic water, ambient occlusion, and atmospheric effects. Supporting Iris-equipped clients ensures your server looks its best for players who value visual quality.

Server Requirements for Iris

Iris is entirely client-side - your server needs no special configuration. Standard 4GB RAM allocations work perfectly. The shader rendering happens on player computers, not your server.

Sodium Compatibility

Unlike OptiFine which conflicts with many mods, Iris is designed specifically to work alongside Sodium. Players get both shader support AND Sodium's massive performance improvements. This combination delivers better FPS with shaders than OptiFine typically achieves.

Shader Pack Support

Iris supports most popular shader packs including BSL, Complementary, SEUS, and many others. Players can choose their preferred visual style while connecting to your server.

Performance Optimizations

Iris implements numerous optimizations that make shaders run faster than on OptiFine. Shadow rendering, bloom effects, and post-processing are all accelerated through modern techniques.

Open Source Development

As an open-source project, Iris receives contributions from the community and maintains transparency. This results in faster bug fixes and broader shader compatibility.

Perfect for Building Servers

If your server focuses on creative builds or architecture, supporting Iris-equipped players lets them appreciate builds with enhanced lighting and materials. Screenshots and videos from your server will look stunning.

No Server-Side Installation

Since Iris is client-only, you don't need to install or configure anything. Just run your Fabric server normally and players with Iris can connect seamlessly.
