Shaders

Shaders help improving the atmosphere and aesthetics of the game and have become more and more popular by players. On this page you will find some information we have collected over time, mostly on how to make them work with Forge Mods. As you might have experienced: Shaders like to be very picky, they make you try every option to get them to work properly, which results in entire evenings being spent outside of the actual Gameplay.

Installing Shaders

Adding Shaders to your game has never been as easy as it is now. (MC 1.10+)

  1. Add the latest version of the Optifine Modification to your Minecraft instance.
  2. Launch the Game
  3. Download your favorite Shaderpack
  4. Add the zip to your Shaderpacks folder (Options > Video Settings > Shaderpacks > Open folder)

Pro Tip: Do not enable or switch Shaderpacks, while playing in a world. It will take much longer than doing so from the Main Menu and potentially crashes your game.

Note to Forge Users: Install Optifine not by running the downloaded jar, but by just adding it to your Mods folder.

Fixing Shaders

In case you aren't playing vanilla or a light-weight Modpack, you will probably have to consult this section.

Your first option is always to try a different Shaderpack. Most of them differ by a lot in their nature, so if one of them crashes often or looks funny, others might work just fine.

Should you find visual glitches, such as eternal darkness, z-fighting in the Sky layer, random Shadows etc, then it's most likely caused by another Mod messing with rendering. Here are some config changes that have proven useful in the past:

  • forge.cfg B:forgeLightPipelineEnabled=false
  • immersiveengineering.cfg B:disableFancyTESR=true
  • botania.cfg B:shaders.enabled=false
  • astralsorcery.cfg Copy the list from S:skySupportedDimensions=<list> to S:weakSkyRenders=<list>
  • psi.cfg B:shaders.enabled=false
