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

• Basic Shaders for Vanilla 1.16 resource pack

• Sildur's Fabulous Shaders resource pack (configuring instructions)

• Depth Shaders resource pack

• More shaders can be found on Modrinth

Installation

1. Go to Options -> Video Settings -> Quality -> Graphics: Fabulous!

2. Download any Fabulous shader pack

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:

• Translucent Spyglass Overlay

• No Spyglass Overlay

Examples of not working core shaders of Vanilla Tweaks:

• Mob Spawn Indicator

• Wavy Leaves

• Wavy Plants

• Wavy Water

Luckily those features can be replicated with OptiFine shaders or other mods, so you're not missing out.

Resource pack developers: you may try to make your pack work in Sodium with this mod or this manifest.

Installation

1. Download a core shader-using resource pack from Modrinth

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 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.
