# Shaders

These are the steps to take to add shaders

### Optifine Shaders

**Most Optifine Shaders compatible** with the [<mark style="color:yellow;">Iris mod</mark>](https://www.curseforge.com/minecraft/mc-mods/irisshaders) iris **doesn't run every Optifine Shader**, while you *could* try the shaders you want Iris suggests [<mark style="color:yellow;">these</mark>](https://github.com/IrisShaders/Iris/blob/trunk/docs/supportedshaders.md) because they are **tested**.

#### Installation

1. Start the Faster Than Light instance
2. Navigate to `Options...` --> `Video Settings...` --> `Shader Packs...`
3. Download the shaders you want ([<mark style="color:yellow;">Recommended ones</mark>](https://github.com/IrisShaders/Iris/blob/trunk/docs/supportedshaders.md))
4. Drag the .zip to your minecraft shader pack screen
5. Set Shaders to `Enabled` in the top
6. Select the shader, click `Apply`

#### Configuration (optional)

1. Click on the shader
2. Click on `Shader Pack Settings` on the bottom
3. Make your wanted changes
4. Click on `Apply`
5. Click on `Done`

### Canvas Shaders

[<mark style="color:yellow;">Canvas Renderer</mark>](https://www.curseforge.com/minecraft/mc-mods/canvas-renderer) is a shader mod optimized for **powerful computers**, these shaders are **not supported** but if you wish to have them make sure to **remove Iris and sodium and replace it with Canvas renderer.**
