It is a Java-based shader pack of Minecraft designed on BSL Shaders of CaptTatsu. It is an excellent tool for Minecraft content creators looking forwards to a cinematic experience. You can enjoy it yourself on your favorite server or with all sorts of audiences. Apart from HDR, you get a cinematic feel due to blur and field depth tweaks.

If you want the shaders to work without hiccups, please ensure that you have the Optifine edition of at least 1.18.x because this pack works properly only on this or older versions.

  5. GreenDragon

    How do you turn off the motion blur? its driving me crazy!

    1. Advan

      you need to go in the setting shaders , shaders option , post process and you got motion blur that you can turn off

      1. GreenDragon

        thank you

  6. CR0WN

    to remove the cartoony sun just turn of the option tht says sun rays

  7. PhysicaInstinct

    i absolutely love this shader
    only thing i wish i could change is the cartoony looking sun
    not a big fan of it
    but overall its amazing!

  8. Kacper Piwowarski

    Cool

  9. PopeDoomer

    This shader is wonderful, but the world has this wavey effect to it, like I’m in a heated climate or had one too many shots. It’s subtle but it’s very distracting and disorienting.

  10. Sanszu

    The shader works perfectly and is beautiful, however the shader has these black boxes over stuff when I move(including me) as if the shadows aren’t working properly, I’ve turned everything in the shadow menu off and on and tried fixing it but I have no clue what to do, because none of my attempts to fix it have worked. Help would be appreciated!

  11. Runaiya

    This is a really beautiful shader (I adore the nebulas) and it runs smoothly on my PC (3060 Ti, 32GB Ram, Ryzen 7 5700X + LexBoost Profile) though I have to turn off motion blurs and sometimes camera sways, but it always lags a lot whenever I open the textbox, inventory and esc menus, drops my fps to less than 5. Tested with AND without Resource Packs yields the same results. Also tested with BSL Shaders and that doesn’t lag at all, only when I’m using AstraLex Shaders.

    1. Runaiya

      I fixed it, not sure if it’s the re-installation of Minecraft or entering fullscreen mode fixes it but it works flawlessly for me now.

    2. agoti

      ugh this shader is soooooo bad

  12. striker

    does it work in fibric ?

  13. Tacticx

    I have a really good computer(dont remember the exact specs), but i still get 0/1 FPS, and even drops the overall performance on my PC even outside of minecraft, any ideas as to what i can do?

    1. Admin

      If your PC performance drops even when Minecraft is not running, it is a problem with your PC hardware or some software that is consuming your resources. Shaders are resource intensive for sure, but only if they are installed and loaded into the Minecraft world. Once installed, shaders become part of Minecraft (like any mod or resource pack), they don’t affect your PC’s performance when Minecraft is closed.

      1. Tacticx

        The performance drop was with minecraft still running, most it was doing was making typing take a couple seconds to update to what i typed, and some issues loading things, but the part that concerned me about that was i checked task manager yet nothing ever seemed to be above 50% usage, despite minecraft running with a pretty tanky shader, which makes the terrible framerate even more confusing to me.
        Yes i am aware i am using a laptop, but is an alienware with some pretty good specs and an 3070, and my old shitty pc, about $800 could(while very much struggling) run some form of shaders with more then 1 fps
        Still got any ideas?
        And yes i lowered the absolute hell out of the effects the shaders had, still never got it higher then 4 fps

        1. Admin

          We can’t help you much as there can be many, many issues with your computer or Minecraft installation. We suggest you try uninstalling the last “things” you have installed in Minecraft one by one, restart and start the world. Remove only one mod or pack at a time, reload and run the world and see if it lags. If so, uninstall the next mod or pack and do so until you find the mod/pack that is causing the lag.

          P.S. 0/1 fps is really terrible for a 3070 unless you have 4GB of RAM and a bad CPU (yes, RAM is very important for Minecraft to play at a stable fps).

  14. limp

    How to you turn of motion blur

  15. Chillman

    Does anyone know if I should switch to a newer version. I’m on one from 5 months ago and in 1.20 I see nothing wrong with the one I have, Do the newer versions fix performance issues?

    1. Admin

      There is nothing wrong with using older versions of shaders, as long as they suit you and work fine. Unless there are new features in new versions that you want to use.

  16. legitjohnson8

    When I click download it is a zip file. What do I do from there?

    1. Admin

      Read the installation instructions on this page.

  17. egg1

  18. Sprite

    How do I disable the black bars that appear when I crouch?

  19. Corbin

    Is there a way to turn off the motion blur? i assume its to save framerate, but it makes it more difficult to see everything around me

    1. WildWizard

      Did you manage to fix it? If so how

      1. limp

        its in the post process settings

  20. Kit

    Is there a download available for bedrock?

  21. Jake

    can i use this in tlauncher?

  22. yosoychipsa

    not a texture pack

    1. Admin

      But no one said it was a texture pack. It is in the Shaders category.

  23. hiiiiiiiiiii

    it is amasing!!!

  24. Gwon009

    Do we absolutely need optifine or Iris?

    1. Admin

      Shaders just don’t work without optifine (or iris).

  25. isaac

    My game just crashes if i boot up the word but my graphics card has the option to go better and when i turned it on it still wouldn’t boot how to fix this

  31. Grizzy

    Why is everything black

  32. Lima

    its not 1.19.4 ready. i realy dont see the shaderpack/folder in the video settings

    1. Admin

      But have you installed optifine? Always read the yellow box in the download section as we always try to provide the most important information there.

  33. hmm..

    evrything worked exept the last step. the shader pack wont show up. ive tried restarting minecraft but still dosent work. is there any way to fix this?

  34. Cipher

    is there a way to turn off the rgb outline of blocks? its cool but not really my thing
    other than that this is awesome

  35. abyss

    What Ram is required to run this?

  36. science_kit

    Hay, in a video of your shaders, the author went to the world setting and moved a “world curve” slider. This is a feature of BSL?

  37. SammahJ

    Love the shader!
    But the birds in the sky (distant images) are a bit weird and distracting from the otherwise beautiful vista.
    Is there anyway to switch off the birds?

  38. Liam

    I was on 5 fps the whole time lol

  39. kyle

    is there an easier way to do this like a direct download

    1. Admin

      We use official download links, we do not have rights to re-upload packs. For this particular pack, the link is technically a direct link. After clicking on the download link, you will be redirected to the official download page, but you don’t have to click anywhere there, the download will start automatically in a few seconds.

  40. Annepizza

    For some reason when i download it and put it in the resorce packs file it doesnt show its there what do i do

    1. Admin

      Maybe because it’s not a resource pack, but a shader pack?)

    2. matej

      but this is not a resource pack
      its a shader

  41. Richerd

    YO TIS IS SOOOOOOOOOOOOOOOOOOOO COOOOOOOL

  42. adam glokler

    YO THAT IS SO COOL

  43. Waddle_D

    ive used this before, i loved it and it works great, but ive come across an issue where when i try to use it and load into a world, instead of showing the in game stuff, it leaves up the dirt wall for the loading screen

  44. EvilHorizon

    This shader is amazing!! The only thing im not a fan of the the screen narrowing while sneaking. Other than that its the best!

  45. Helvy

    Shaders is cool!

  46. Jack

    I’m surprised my potato PC did not explode, but I did make some scrambled eggs off of the heat

  47. Zen

    For some reason this shader turns all letters on signs into blocks and I can’t read them at all. Any option to change / fix it myself? I looked inside the settings but there are so many options that I can’t find anything :/

  48. Lulerich

    Lol!

    1. Admin

      Read step 3 of the “How to install” section on this page. Most likely the problem will be in it.

      Shader packs are resource intensive. They will definitely lower fps.
