    Okay so i was finally able to join a server but all the blocks and stuff are white washed and the water looks like a white version of the normal water. Only the sky texture looks like its supposed to

    1. Sensa1_

      I think you turned on white-world. You should be able to turn it off in one of the settings tabs.

  2. guest

    i can’t select it, when i go to the video settings it won’t let me click it how do i fix that?

    1. guest

      i can’t select the shaders button i forgot to say that

      1. Some Random Idiot

        maybe because youre not using optifine?

        1. knockoff

          so how do you ‘use’ optifine then? got it downloaded but im having the same drama..

    2. CRElb0w

      your not using optifine then

    3. memerguy

      make sure you have antiscopic filtering off

  3. RaZer

    Is this for Minecraft Java or Minecraft Bedrock?

    i have Minecraft Java

  4. CaptainRex09

    Hi your mod/resource pack/shadier pack, looks very cool but when I try putting the file in the resource pack area it doesn’t work, please help.

    1. Admin

      You should put it in shaderpack folder, not resourcepack.

  5. Mac no optifine

    If i installed this would it explode my mac?

    1. Admin

      Depends on the hardware of your Mac, but Macs are not suitable for games with high hardware requirements. Shaders are resource intensive.

  6. Manky_Hamster

    hi, the zip seems to no longer contain the resource pack – is there a separate place I can get this please?

    1. Admin

      “No longer contain the resource pack” – are you sure you are checking what you need? This is a shader pack, not a resource pack.

      1. Manky_Hamster

        yes .. I was following the instructions for application as above:-
        the file at step 6 marked with (unzip me) isn’t downloaded from the link above
        step 11 being applying the shader pack is fine
        but the file at step 9 isn’t there – unless it’s the same zip file – in which case it’s not showing in the resource packs list under options

        1. Admin

          We’ve personally tested everything and if you are using Minecraft version 1.16+ ignore step 9 as ComplementaryResources are already integrated into ComplementaryShaders. Without extracting, drag & drop the ComplementaryShaders .ZIP archive into the Shaderpacks folder. P.S. We will update the instructions for new versions as soon as possible.

          1. Manky_Hamster

            thanks for your help – I think I have everything working OK for overworld – it’s just the End seems to be missing the aroura borealis – I only get a grey sky … would you know if that’s an setting? tried a few things but no luck as yet.

  7. QT Bluey6

  14. Axxy

    1. Admin

      Upgrade your PC. Shader packs are resource intensive.

  15. Sami

  16. Donovan Veasey

    1. Admin

  17. GHEORGHE NICHITUT

  18. bartus_321

    1. Admin

      Have you even enabled the shader pack in the game settings? Have you read the installation guide on this page?

  19. Angie

    For some reason, this doesn’t work? I don’t know what I’m doing wrong. It just doesn’t work.

  20. sam

    it crashes my game when i open up a world and says something about an unexpected error on the launcher?

  21. floydbarstool

    i put the resource pack in but it doesnt do anything.

    1. Admin

      This is not a texture pack..
      These are shaders, which is a completely different thing.

    2. TJ Rozzelle

      I think you have to put it in ShaderPacks

    3. Turbo_s1ayer

      its a shader not a resource pack

    4. the_caped_Galaxy

      u need to put it in the shaders folder

  22. Ardesqu

    i like it
    its soo good

  23. notmyname

    When I loaded it up it was fine, but after a couple of minutes it just freezes my game. I have noticed the game still works, just all of the visuals are locked in place. I have tried 2 times restarting minecraft and it still wont work. Is there a way to fix this or am I just going to have to not play with the shaders?

    1. caza1027

      yea thats what happens to me and it just freezes but theres no sound and so i have to restart mc and its really anooying. but what u can do is go to the launcher and go to installations and click on optifine and press edit. next u press more options and theres the piece of code or something that will probably say 2G. change the 2 to a bigger number like 5 or something and it will give it more ram and ur game might not freeze

      1. D diddy

        thanks caza
