BSL Shaders 1.21 / 1.20

Any player of the popular game Minecraft would have to admit that the standard lighting effects leave a lot to be desired when it comes to realism. While realistic graphics are not a part of the world design in the game, the smooth lighting and graphic effects, even when set to their highest level, aren’t exactly the best they could be. The graphics could use just a touch of realism to add to the game’s atmosphere, and its overall aesthetic appeal. When it comes to embellishing the graphics of the game, shaders are the way to go. Especially the BSL Shaders. This shader pack stands out for its unique features as a pack designed specifically for Minecraft: Java Edition. Its features include real-time shadows, volumetric light, ambient occlusion, customizable clouds and water, bloom, etc., in order to add a sense of realism to the environment of the game.

There are also additional effects available, like motion blur, world curvature, depth of field, specular and normal mapping, and celshading, just to name a few examples. There are no perceivable glitches or bugs throughout the shader pack. The colors come with a boost and saturation alteration, which adds to the atmosphere, particularly for the Nether; the bright, eye-catching colors mixed with the shadows create a very visually pleasing experience. That being said, the BSL Shaders requires a lot of additional resources to your PC and it is not designed for low-spec PC’s. But, as this pack is, quite possibly, the best way to embellish the graphics of your game, it’s well worth any additional installations. To ensure you get the highest quality visuals, BSL Shaders requires Optifine. If you do not already have this mod installed, you will need to do so in order to get the very best experience from this shader pack.

BSL Shaders should be compatible with all of these Minecraft versions: 1.21.11 - 1.21.10 - 1.21.9 - 1.21.8 - 1.21.7 - 1.21.6 - 1.21.5 - 1.21.4 - 1.21.3 - 1.21.2 - 1.21.1 - 1.21 - 1.20.6 - 1.20.5 - 1.20.4 - 1.20.3 - 1.20.2 - 1.20.1 - 1.20 - 1.19.4 - 1.19.3 - 1.19.2 - 1.19.1 - 1.19 - 1.18.2 - 1.18.1 - 1.18 - 1.17.1 - 1.17 - 1.16.5 - 1.16.4 - 1.16.3 - 1.16.2 - 1.16.1 - 1.16 - 1.15.2 - 1.15.1 - 1.15 - 1.14.4 - 1.14.3 - 1.14.2 - 1.14 - 1.13.2 - 1.13.1 - 1.13 - 1.12.2 - 1.12 - 1.11.2 - 1.11 - 1.10.2 - 1.10 - 1.9.4 - 1.9 - 1.8.9 - 1.8.8 - 1.8.6 - 1.8.1 - 1.8 - 1.7.10 - 1.7.9 - 1.7.4 - 1.7

    1. Admin

      Well, shaders are resource intensive. If you have a weak hardware device, you will not be able to run shaders with decent fps.

  8. Al

    Is this the way to install these BSL Shaders for the iOS?

    1. Joemama

      Bro its Java edition

  9. Turtle

    Does it work on mcpe

    1. Admin

      Nobody here said it was compatible with mcpe. Most shaders don’t. BSL Shaders only works with optifine, which is a Java-only tool/mod.

  20. Evan

    Are there any resource packs that you would recommend us to use along with the BSL Shaders?

    1. mp

      i like vanila PBR.. its basically the same but adds metal effects too metal blocks and the lighting is pretty awesome in conjunction with the shader

  21. Breloom

    I wanted to know if there was a way to fix this:
    I have used BSL Shaders for a while now and still cant seem to fix this thing where sea grass at the very top of the water block (The first block that the water covers) makes the shaders water feature not work and its just patches of the vanilla water mixed with the shaders water and it really bugs me. Is there a way to fix this?

    1. Serena

      I’m having the same glitch.. did you ever find a fix? :(

  22. Sam Adriana
