SEUS / Sonic Ether’s Unbelievable Shaders 1.20 / 1.19

A defining feature of Minecraft is its visual aesthetic. The block style and simplistic graphics are now synonymous with the game and give it a retro gaming feel. The simple styling and play make the game easily accessible and popular across a broad demographic but, what do you do when it no longer satisfies you and eventually starts to irritate you? There is a solution, Sonic Ethers Unbelievable Shaders. Sonic Ether’s Unbelievable Shaders, or simply SEUS, completely transforms the games graphics and takes Minecraft to a whole new level. This shader pack brings the game to life by highlighting the natural properties of different game components. SEUS adds an element of reality to the graphics that really augments vanilla game play. Water appears to flow, large expanses of water appear homogenous and plants seem alive and move with the breeze. SEUS also enhances the night feel of the game with its play on shadows. The most transformative feature of the shader pack is lighting. The standard lighting used in vanilla game play is stark, offers minimal variation and adds little to the gaming experience. The default light color used is yellow light and this applies to most artificial light sources (fire, torch, glow stone) as well as natural light sources like the sun. The shader pack goes back to basics adding color and nuance to each light source.

The result is immediately obvious. Torchlight is easily distinguishable from sunlight, moonlight is very different to the lighting produced for lava. It is not just the colors that make the difference. Shadow definition and placement combine to increase the intensity and impact of the enhanced lighting. Attention to detail is evident. Even small blades of grass create their own shadows at angles corresponding to the position of the Sun. If the monotony of the vanilla game lighting has made the game feel lacking, SEUS is a quick fix that will add vibrancy and breath life back into the game. Another high impact feature of the shader pack is sky textures. Gone are the standard, block style clouds in their predictable formations. In their place SEUS introduces ethereal clouds that move in the sky and continually change. The shader pack transforms the sky replacing the floating blocks with soft, hazy clouds. The sky now feels real rather than a blue space filled with floating white flooring. Despite the obvious contrast between the original pixilated design of Minecraft and the very realistic design offered by the shader pack, both design elements actually work well together. By incorporating authentic lighting and weather into the game the shader pack adds to the game rather than detracting from it. It comes as no surprise that in order to run Sonic Ether’s Unbelievable shader mod pack you need a computer that can handle the enhanced graphics. Older computers with insufficient memory and processing speed might struggle to display the enhanced graphics and negatively impact your game play.

Sonic Ether's Unbelievable Shaders (SEUS) should be compatible with all of these Minecraft versions: 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 - 1.6.4 - 1.6.2

  3. musles31

    Hey man, these seus shaders are not downloading. The link is broken or too slow, refresh now.

    1. Admin

      On our side it works fine.

  4. Ashton

    Is there anyway to remove the part where the Sun becomes darker whenever I am looking at it, Aswell as the part where I keep getting flash banged by the sun everytime I jump/Move around?

    1. Juice

      I really need the answer to this! I also had an issue with the shadows constantly changing which I fixed by turning the shadows off. Sadly at the moment any light source dulls the light if I look at it. I’ve tried disabling a lot of different things but I cannot see anything that would affect this. I really hope this gets answered because I really want to use this on a PVP server.

  5. luisreyes

    wow the shaders are spectacular

  6. jackson

    hay can someone help me, ive downloaded the 10.2 and the 1.0.1 and none of them look like the first three pictures, i want to see the wood texture, idk if im just not downloading the right versions or what, pls help.

  21. Stargaz3

    this is one of my favorite shaders and I’ve had zero technical issues, but night vision potions don’t work while im using this shader, is there a setting i can change or is this intended?

  22. PearlJim

    Is there a way to get rid of the slight blurriness I’m noticing? feels like there is a very slight fog throughout the entire world.

  23. Mysterious_Pickle

  30. T

    What is the texture pack in the middle picture?

    1. Princess Celine of Lanover

      I believe it is meteor or modern arch they look very similar

    2. Igor

      R3D.CRAFT most likely. The texture of the cow and wood is exactly the same there.

  31. Shaders

    so butyful i love the shaders how did you make it?

    1. Haziq

      I’s so good

  32. D

    hay i put the file in the shader packs folder and got optifine but its not apering in the saders tab can you please help

    1. tatas

      go to options/video settings/shaders and click on the seus you can modify it by pressing the buttons on the right and the config button on the bottom right make sure you press done when you are finshes

  33. bb

    nothing loads people’s problems go unanswered 0/10

    1. Admin

      The answer will be given after a detailed explanation of the problem. How can we recommend something to people who just comment “doesn’t work”? And 90%+ of the problem occurs when optifine is not installed or optifine was installed for an older version than you downloaded the shader pack. And if this is a problem, we cannot help. You need to know which version of Minecraft you are playing on so that you can download the stable version of optifine for that particular version of Minecraft and then select a shader pack that works with that version of optifine & minecraft. Again, optifine and most shader packs are java-only, they don’t work or load in the bedrock version.

  34. m

    i have the 1.17 version and it doesn’t allow me to ad the pack, it says “failed to copy packs” someone please help me

  35. Eitann

    Whenever I add on a resource pack on to this shader, the world turns to a blush tint and become sort of fuzzy. I’m now seeing that whenever I use the 2 I get a GL error. Does anyone know what’s wrong or how to fix this?

  36. E

    do i need to unzip it?

    1. Aaron

      No… just drag the file into the shaderpacks folder and then you should see it in the shaders menu in minecraft

  37. GhostGamer25

    Its sooo cool but you cant play because of the lags

    1. Azmyuth

      i think its because this is meant for people with actually good computers and not potatos… im crying in the corner because im using a potato pc

      1. kashunbb

        my pc i old not potato from the 2000s so like 20-16 years old

  38. Viper_Saeed

    Hi please answer i download this shader and so much shader but when I use shader textures wont changed i just have shadows and water quality its all allowed shader gives me im using Windows 10 home edition it wasn’t happened in my old laptop but in my new pc it wont work I download everything I update my drivers and everything you think but textures like normal Minecraft please help me im using java 1.16.5

    1. Admin

      Please familiarize yourself with the difference between a shader pack and a texture/resource pack before downloading.

  39. Erde

    I have the Windows 10 edition and there the highest version is 1.16.220
    I downloaded Optifine, but the “little green arrow” is not there, up until that everything went as described
    I downloaded this shaders pack, but when I open the Launcher, the highest version that will open at least is 1.12.2
    And when I go to Options and Video Settings there, there is no “Shaders” button

    Help please? :)

    1. Admin

      Windows 10 is the bedrock edition, which, if we are not mistaken, does not yet support optifine (optifine only works with java).

  40. Rax

    This pack since yesterday is now flashing all the floors going transparent and then opaque again every 1s or so it is SUPER distracting and I can’t concentrate. I have tried uninstalling the pack and reinstalling the pack but it made no difference :'(

    Please help!

  41. Katy

    Hey, like this shader but it makes my screen look… cloudy? Not nearly as clear as the pics

  42. Marcoxdish

    I dont have the “raytracing Options” Button, Does it not work on Minecraft Java Edition? My Graphic Card is the RTX2070Super

  43. Evelyn

    I’ve done everything as stated and when the world loads up, it gives me –
    [Shaders] Error: Invalid program “gbuffers_hand”
    [Shaders] Error: Invalid program “gbuffers_water”

    Any help would be much appreciated! Thank you.

    1. Admin

      If you are using nvidia graphics card try changing java settings to “high performance nvidia processor” in nvidia control panel.

      1. Dilly

        Thank you! This worked for me, as I was having same problem. Fixed and beautifully shaded :)

      2. Keeith

        yo, i’m here as well for the same problem, my point is just that I’m not using nvidia graph card, I’m just using my Intel i5 10600 integrated graphics, how should I fix it?

        1. Admin

          The problem with shader packs is that they are resource intensive and will probably not work properly with integrated graphics or will lag a lot. We do not recommend using shader packs with integrated graphics.

        2. young

          lmfaooooo you need an actual graphics card man im surprised you can even run minecraft vanilla on integrated graphics

      3. tj

        i have a macbook and it looks like i am using the Apple M3 Max (40-core GPU). when i load the shaders it shows up blank what should i do

  44. Evan

    it took me 250 hours to try to install and still did not work >:(

    1. Admin

      What exactly is your problem? Is it giving you some kind of error? Shader not listed in game settings? or something else? A little more information from you will help get a solution much faster.

      1. LM-Covu

        ive jus t downloaded it and when i booted it up on minecraft everything turned white lol

  45. JustNaxy

    yo this shader is awesome!

  46. CommonerGold047

    How much Vram is required?

      1. Bomberanian

        That doesn’t help


    I tried the link on different web browsers but nothing is downloading when I check the box and then click download. Double clicking doesn’t work either. The browsers I tried this on was Chrome and Microsoft Edge. I have java and optifine, any ideas as to why nothing is downloading? There seems to be no answers in the comments.

    1. beanos

      try to use Vivaldi.
      itz good

  48. Skeleton0803

    Does it work with every version?

  49. Vision Duwadi

    Plz send me the requirement for this resource
    requirement of laptop or compter

  50. SCSpencer19

    I tried the download link but it doesn’t work. The page freezes, and when I try to refresh it, it says “ unexpectedly closed the connection”. Does anyone know of any ways to fix this?

    1. Admin

      It works just fine for us. Be sure to read & check the box next to “I have read and accepted the EULA” on the sonicether website.
      Unfortunately, there is nothing we can do with these links as we only provide official links. In other words, if the link doesn’t work, we won’t be able to fix it. We can just wait for the author to fix it.

      1. Brawl

        its very good resurce pack

  51. Mytt

    Which resource pack/settings are the screenshots taken with? I particularly like the fur effect of the cow, but it doesn’t look like that in my game

  52. 128ajb

    i have tried using the shaders, but i had a graphical bug where everything was all one color and the outlines of the blocks were the same color as everything else. IE on the land above ground everything was green

    1. Animegirlgaming

      Same. On Windows 10? Try getting a new GPU.

  53. Helpless

    I cant get it to change the texture, They still use MC default stone and wood and glass. looks nothing like it except for the lighting part.

    1. Joshua Th3B3ast

      Im 90% sure they used a texture pack to go with the shaders. You would have to install the texture pack they used for it to look the same as the pictures.

  54. Raghibul haque

    Is this work for minecraft mobile??

    1. yessssszzzz

      no lol

    2. Ragball

      bedrock moment

      1. MattExists

        Pocket edition moment more like :|

      2. Outdutidcugi


  55. Chey

    I absolutely love this shader, especially for the water and rain. Just one thing that does make me a little sad though, soul torches, and soul lanterns don’t illuminate at all with it. (unsure if this also applies to the soul campfires but it probably does as well) I know they aren’t as bright as their regular counterparts, but a little glow would be nice for the aesthetic!

  56. Erwin Moreo

    Wow so cool
    Dats minecraft shades

  57. Dave

    I got the shaders working great but it keeps saying openGL error 1281 (invalid Value) how do i fix this

    1. Animegirlgaming

      Try updating video drivers

  58. Ian

    Once I went to the download page and checked the box and pressed the button to download the download did not occur. What should I do in order for it to dowload?

    1. Admin

      Works great on our side. We just checked it manually.
      Maybe try another browser and see if it works.

      1. Ian

        Still doesn’t work, I have even tried it on different devices. Any other ideas?

  59. James

    Hello, I got the shader to work, but it just changed the clouds, lights and water.
    Nothing of the blocks looked like on the pictures, any idea why that could happen?

    Thank you.

    1. Admin

      Shader packs don’t change the textures of blocks or items, they just add realistic lighting effects, shadows, etc.

  60. Sarah

    Hi there!

    Tried this shader pack with CMR REALISTIC X256 Resource Pack because it suggested it, but I couldn’t get the shaders to work using the instructions above. Got them to show up in the Shaders menu in-game, but when I clicked on it to load them, every element came up as “Error: Invalid Program” in the text window.

    Is there something I’m missing that I need to have?
    How can I make this shaders pack work?

    Any advice would be greatly appreciated!
    Thank you! :)

    1. Admin

      Shaders are heavy add-ons and most likely won’t work with integrated graphics.
      We can’t post links here, but there are a few working tutorial videos on youtube you can watch and fix your issue.
      Just make sure these videos were uploaded in 2020)

      1. Sam

        What is the texture pack used in the images?

  61. naaya

    does not work with ryzen 7 3700x + radeon 5700 xt, says incompatible graphics card

    1. Kile

      you might need to update your GPU drivers from AMD website, get the latest adrenalin software from amd’s website, dont use other drivers for ur gpu, i have a ryzen 3 3100 + rx 5500 xt and it works fine

  62. Fairyateralt

    Awesome, SO glad i did this!
