Shaderpacks installation

import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem';

:::note Shaderpacks might be referred to as shaders in the following guide. :::

1. Install selected shader mod or OptiFine. You may need a modloader. :::warning OptiFine is a highly unstable mod. We do not recommend using it with other mods. Try alternatives instead. :::
2. Run Minecraft :::note This will create a new folder called shaderpacks in the Minecraft game directory. :::
3. Download shaders from websites such as Modrinth or CurseForge.
4. Move the downloaded shaders to the new shaderpacks folder in the Minecraft game directory. :::info[Opening the Minecraft game directory]
   1. Click the folder icon in Legacy Launcher.
   2. Click Open version-name directory.
      ::: :::tip Some shaders mods allows you to "drag" a new shaderpack to Shader Packs in-game menu instead. :::
5. Run Minecraft (if closed) and click Options.
6. Click Video Settings. :::note After installing most shaders mods, there will be a new Video Settings layout. This confirms that shaders mod is working. :::
7. Click the new Shader Packs (or Shaders) button.
