Backward Compatibility: All existing ShadersMod / OptiFine shader packs should work as is in Iris, without any modifications.

Vanilla + Sodium + Iris Shaders: Iris offers something that was not present in selected fabric mods: support for existing custom shaders based on both Sodium and Vanilla. Thanks to the shader stack, you get incredible frame rates without the need for expensive hardware or experimental game mods. The extra processing done by Iris only reduces performance by 10-15%, and even with Na installed, Vanilla's performance is much better. Performance, even with Na installed. This is directly reflected in the shaders: most common shaders run reliably at 60 frames per second or higher, even on 5-6 year old hardware.

How to use.

After installing Iris, make sure that it is set correctly in the video settings in Minecraft. The Video Settings menu should look like this:

You will notice that the menu has completely changed. This is a rework of the video settings menu provided by Sodium: the General and Quality tabs have all the usual settings for vanilla Minecraft and can be changed to your liking; The settings on the "Performance" and "Advanced" tabs should not be changed most.

Shader packs are managed on the Shader Pack tab. The shader pack menu looks like this:

This menu displays the shader packs in the shader pack folder. Drag and drop shader packs into this menu or click on the "Open Shader Pack Folder..." button to add a new shader pack to the open folder. After adding the shader pack to the shader packs folder, click the Refresh button on the right top corner to refresh the list of shaders. To select a shader pack, click on "Shaders": Click on "Disabled" to enable it. Then click on the shader pack you want to enable to select it and click the Apply button to activate the selected shader.

In the example below, "Additional Shaders" have been successfully enabled. Note that the enabled shader font has changed to yellow - this is used to indicate that the shader is indeed enabled:

< p>After activating the selected shader, click on the "Shader Pack Settings..." button to configure the shader.The shader pack settings menu looks different for each shader because the available options are determined by the shader itself. For example, if the completion shader is enabled, the menu looks like this

Here you can edit the shader package options provided by the shader itself. The options in the menu should be exactly the same as those you get when loading the shader into Optifine. However, there are a few additional functions in the top right corner of the menu:

Import Button: Import Button: Loads a shader configuration file (.txt format) into the currently enabled shader. When you click this button you will be prompted to select a file. This is useful for loading custom shader settings found on the Internet.

 Export Button: Exports the active shader settings to a .txt file. Useful for sharing custom shader settings.

 Reset Button: Hold LEFT SHIFT and press this button to restore the default settings for the selected shader.

When you are done configuring the shader, Click the Apply button to apply the changes. You will now see a "Shader Pack List..." button to return to the list of shader packs, or click the "Done" button to return to the video settings menu.

You can now load the world and play Minecraft using shaders. During gameplay, keyboard shortcuts are available to quickly control shaders:

Pressing "O" opens the shader pack menu with a transparent background, allowing you to see changes to shader settings in real time.

Pressing " K" turns shaders on and off.

Pressing "R" reloads the currently active shader package.

These keyboard shortcuts can be remapped to other keys of your choice in the Controls menu.

These shortcuts can be reassigned to other keys of your choice in the Controls menu.
