# Install OptiFine shaders ### OptiFine and Iris shaders OptiFine-compatible and Iris-compatible shaders are supported by default as the mod [Iris](https://modrinth.com/mod/iris) is in the modpack. #### Installation 1. Open Minecraft with Fabulously Optimized installed 2. Open `Options...` → `Video Settings...` → `Shader Packs...` 3. Download any shader pack from [Modrinth](https://modrinth.com/shaders?g=categories:iris) or [CurseForge](https://www.curseforge.com/minecraft/search?page=1\&pageSize=20\&sortBy=relevancy\&class=shaders) 4. Drag the ZIP file into the shader pack screen 5. Select the shader, make sure *Shaders* is set to enabled and click `Apply` 6. The shader has been applied! If you run into any problems with shaders, [please report them here](https://github.com/IrisShaders/Iris/issues). #### Configuring settings 1. Click a shader 2. Click `Shader Pack Settings...` below 3. Adjust settings as needed 4. Click `Shader Pack List...` 5. Click `Done` Looking for OptiFine's internal shaders? Try [internal-shaders](https://modrinth.com/shader/internal-shaders) (shader), [Simply No Shading](https://modrinth.com/mod/simply-no-shading) (mod) or [Flat Lighting](https://modrinth.com/mod/flat-lighting) (mod). ### Fabulous shaders "Fabulous shaders" are vanilla shaders that work by enabling *Fabulous!* graphics in video settings and getting a specific resource pack. *May or may not work in FO.* * [Fabulousity shader resource pack](https://github.com/ScottoMotto/Fabulousity#fabulousity) {% embed url="" %} * [Basic Shaders for Vanilla 1.16 resource pack](https://github.com/bradleyq/mc_vanilla_shaders#basic-shaders-for-vanilla-116) {% embed url="" %} * Sildur's [Fabulous Shaders resource pack](https://sildurs-shaders.github.io/downloads/) [(configuring instructions)](https://sildurs-shaders.github.io/install/#fabulous) * [Depth Shaders resource pack](https://github.com/onnowhere/depth_shaders/releases) * [More shaders can be found on Modrinth](https://modrinth.com/shaders?g=categories%3A%27vanilla%27) #### Installation 1. Go to `Options` -> `Video Settings` -> `Quality` -> `Graphics: Fabulous!` 2. Download any [Fabulous shader pack](https://modrinth.com/shaders?g=categories%3A%27vanilla%27) 3. Move the shader pack to `resourcepacks` folder or drag it into the resourcepacks screen 4. Apply the resource pack in resource packs screen ### Core shaders "Core shaders" are a kind of vanilla shaders utilized by resource packs to adjust the vanilla HUD and add special effects to specific blocks. These usually do *not* change landscapes overall and *may or may not work in FO.* Examples of working core shaders of [Vanilla Tweaks](https://vanillatweaks.net/picker/resource-packs/): * Translucent Spyglass Overlay * No Spyglass Overlay Examples of **not** working core shaders of [Vanilla Tweaks](https://vanillatweaks.net/picker/resource-packs/): * ~~Mob Spawn Indicator~~ * ~~Wavy Leaves~~ * ~~Wavy Plants~~ * ~~Wavy Water~~ Luckily those features can be replicated with [OptiFine shaders](#optifine-shaders) or [other mods](https://wiki.download.fo/adding-more-mods), so you're not missing out. **Resource pack developers**: you may try to make your pack work in Sodium [with this mod](https://modrinth.com/mod/sodium-core-shader-support) or [this manifest](https://github.com/CaffeineMC/sodium-fabric/pull/2206). #### Installation 1. [Download a core shader-using resource pack from Modrinth](https://modrinth.com/resourcepacks?f=categories%3A%27core-shaders%27) 2. Move the resource pack to `resourcepacks` folder or drag it into the resourcepacks screen 3. Apply the resource pack in resource packs screen 4. See if it works. * If yes, enjoy! * If not, it is recommended to use OptiFine shaders or other mods for the same purpose. * You may, alternatively, disable Sodium and related mods if you really want them to work, but that will harm your performance too. ### Canvas shaders [Canvas Renderer](https://www.curseforge.com/minecraft/mc-mods/canvas-renderer) is a mod that provides a new type of shaders that may be better optimized for powerful computers. Canvas shaders are **not supported by default on FO**. By replacing some mods, you can still make them work, however.
