2. In Minecraft's main menu, click on Options...

3. Click on Video Settings...

4. Click on Shader Packs...

5. Drag the zip file you downloaded in step 1 to the screen you opened in step 4

6. Select the shader

7. Make sure Shaders is enabled

8. If you want to configure the shader, use the Shader Pack Settings... button

9. Click on Apply

If you run into any issues, please report them on the Iris issue tracker.

Internal Shaders

To get OptiFine's internal shaders, you can use:

• "internal-shaders" shader

• "Simply No Shading" mod

• "Flat Lighting" mod

Fabulous Shaders

Fabulous shaders are vanilla shaders which work by enabling Fabulous! graphics in video settings.

Examples of Fabulous Shaders include:

• Fabulousity (preview on YouTube)
• Basic Shaders (preview on YouTube)
• Sildur's Fabulous Shaders (configuration instructions)
• Depth Shaders
• More from Modrinth

Core Shaders

Core shaders are used by resource packs to adjust the HUD and add special effects to some blocks. Not all core shaders are compatible with FO.

Examples from Vanilla Tweaks include:

• Translucent Spyglass Overlay

• No Spyglass Overlay

• Mob Spawn Indicator (does not work in FO)

• Wavy Leaves/Plants/Water (do not work in FO)

• More from Vanilla Tweaks
• More from Modrinth

The ones which do not work may be replicated by adding a mod.

For developers: You may make your resource pack work with the Sodium manifest or with the Sodium Shader Support mod.

Canvas Shaders

Canvas shaders are a kind of shader optimized for powerful computers, to be used with the Canvas Renderer mod.

Examples include:

• Lumi Lights
• More from Modrinth

Canvas shaders are not supported by FO, but you can replace some mods to support them:

1. Disable the following mods:

   • Sodium

   • Sodium Extra

   • Reese's Sodium Settings

   • Iris

2. Add the Canvas Renderer mod
3. Install the shader you want
4. Enable it from Options... → Video Settings... → Canvas → Pipeline Options → Pipelines
