Some question aren't asked that frequently, but I'll just add it for no reason.

What are the requirements?

I got a config (shader options file). How do I install it?
  • Put the config inside .minecraft\shaderpacks
  • Rename the config to the shaderpack's name (extension included, ended with .txt)
    BSL v7.1.zip uses a config named BSL v7.1.zip.txt.
    BSL v7.1 uses a config named BSL v7.1.txt.

Can I run this in Minecraft 1.x.x?
    Shaderpacks are usually not affected by Minecraft version. The lowest version I recommend is 1.12.2 though. Older than that, it's still useable but it have some issues.
  • 1.12.2 and below :
  • - Beacon beam still cast shadows. (minor issue)
  • 1.11.2 and below :
  • - Auto Exposure flickers quickly and doesn't work with TAA.
    - Rain / snow won't show due to very low opacity.
  • 1.7.10 :
  • - Outdated block ID format, some blocks may behave like normal blocks.


There is only one zip (per version). Where can I get lower / higher quality of it?
    You can change it through Shader Options. It allowed me to set up multiple quality "Profiles" in one zip, which allows easier distribution.

Should I change render quality and shadow quality in Shaders menu?
  • Render quality, you can lower it for sure. However, I'd recommend using the built in anti-aliasing (FXAA or TAA) instead of higher render quality since it's cheaper.
  • Shadow quality, don't. You can change it through shader options.
    Shadows > change Shadowmap Resolution and/or Shadow Distance.


My top half of the sky is broken.
    Video Settings > Details > enable Sky.

I don't bring light sources and caves are too dark.
    Video Settings > change Brightness.
    This shader uses similar brightness to vanilla on caves (unless you change certain settings).

I turned on Round Sun & Moon and I still see vanilla sun & moon.
    Optifine doesn't support vanilla sun & moon toggle based on shader options, you need to disable it manually.
    Video Settings > Details > Disable Sun & Moon.

Why my fast leaves aren't solid?
    The shader doesn't do lighting on transparent surfaces to improve performance. However the transparent part of fast leaves still counts as transparent, leaving those parts unshaded. This is why I decided to force disable fast leaves.
    Video Settings > set Graphics to Fancy,
    Video Settings > Details > set Trees to Default / Fancy.


The shader is blurry. I don't like it.
    Shader Options > Post Process > reduce Bloom Strength, or disable Bloom.

The shader is too blue / bright / anything else related to color and brightness.
    Shader Options > Color > change the settings as you see fit.
    You can also try Shader Options > Post Processing > Color Grading & Tonemap Config

Why some blocks like glowstone and sea lantern are tinted yellow?
    I tinted it to make it look more consistent with the blocklight color. You can disable it through shader options.
    Shader Options > World > disable Emissive Recolor.

Why everything looks dull at night/when raining?
    I tinted everything to give a more atmospheric feel. Again, you can disable it through shader options.
    Shader Options > World > disable Desaturation.

I use resourcepack with specular and normal map, but nothing happened.
    Due to performance cost, extra effects which can be achieved with specular and normal map are disabled by default, you can enable it through shader options.
    Shader Options > Visual > enable Resource Pack Support.

I enabled Black Outline and I see patterned outlines on water and lava. It's disturbing.
    Shader Options > Waving Blocks > disable Water and Lava.

My screenshot is bright for no reason. It's fine ingame though.
    You have both Screenshot Size and Auto Exposure enabled. Disable Auto Exposure, you can change the expsure manually.
    Shader Options > Post Processing > Color Grading & Tonemap Config > change Base Exposure
