Iris Shaders – a mod for Minecraft

What does Iris Shaders do?

Iris Shaders adds support for shader packs: dynamic lighting, shadows, reflections and other visuals in compatible Minecraft Java.

Shaders without game change

Iris adds the infrastructure for Shaderpacks to Minecraft Java. By itself, it does not make the world cinematic: lighting, color correction, reflections, shadows and effects of water are given by a specific shaderpack. One set can almost not differ from the usual graphics, the other - seriously load the video card. Shaders are selected separately from Iris, so that image quality and performance can be adjusted.

Compatibility with graphical modes

Iris is often installed with Sodium to combine shader support and optimized rendering. Other mods interfering with rendering may have their own requirements. In particular, when using Distant Horizons, shader packs that can work with remote LOD geometry are needed; a conventional package of such effects does not guarantee. Check not only the Minecraft number, but also the compatible versions of all the graphics bundle components.

How to pick up a shaderpack

Start with a moderate preset, then separately include shadows, reflections, surround lighting and additional effects. When performance drops, it is easier to find the cause if you do not switch several parameters at once. Some shaderpaks work differently with water, weather and dimensions. Evaluate the picture in the worlds you play, not just from advertising screenshots.
