Documentation for Users
Sodium Core Shader Support allows resourcepacks to replace sodiums core shaders with their own. That does not mean, that
this mod makes every vanilla resourcepack work on sodium. The resourcepacks will only work if they specifically state, that
they are compatible with sodium core shader support.
If you are using a supported resourcepack you can simply activate it like any other resourcepack.
Resourcepack incompatible
Sodium may display the message The following resource packs are incompatible with Sodium in the top right corner after
reloading resources and listing your active core
shaders. This message will always appear, even if the resourcepack supports sodium core shaders and can be ignored.
List of Resourcepacks
This is a small list of resourcepacks that work on sodium. If you have created a resourcepack yourself feel free to
open an issue on my github to add it to this list!
- [Energy Shaders \[Java\]](https://modrinth.com/shader/energy-shaders-java)
- [Night Vision Shaders \[Java\]](https://modrinth.com/shader/night-vision-shaders)
- Re-Shaded (since re-shaded version 1.3)
Documentation for Shader Developers
It is important to understand that your vanilla shaders cannot just be copied to sodium shaders. Sodium has their own shaders
for blocks and clouds:
- assets/sodium/shaders/
| - clouds.fsh
| - clouds.vsh
| - blocks/
| - block_layer_opaque.fsh
| - block_layer_opaque.vsh
| - include/
| - fog.glsl
| - chunk_material.glsl
| - chunk_matrices.glsl
| - chunk_vertex.glslUnless you want to change sodium clouds the blocklayeropaque are usually the most important ones.
You should not have to touch chunkmaterial.glsl, chunkmatrices.glsl and chunk_vertex.glsl unless you know what you
are doing.
Retrieving sodium shaders source code
To retrieve the sodium shader source code for a specific sodium version, download the .jar file of that version and
extract it like a .zip archive. Inside the extracted archive you will find a assets folder containing the directory
structure mentioned above.
blocklayeropaque
The blocklayeropaque is used for all blocks and block entities. The vanilla minecraft equivalent is terrain.fsh
and terrain.vsh (In older versions of minecraft the equivalent is rendertypesolid, rendertypecutout, rendertypecutoutmipped, ...).
Additionally, sodium core shader support adds a few defines in the sodium shaders blocklayeropaque.fsh
and blocklayeropaque.vsh for some terrain-types:
RENDERPASSSOLID: Solid BlocksRENDERPASSCUTOUT: Blocks like leaves, grass, glass, ...RENDERPASSTRANSLUCENT: Blocks with actual transparency, e.g. water, honey, slime, ...
Furthermore, the define SODIUMCORESHADER_SUPPORT will be present in all shaders (mc >= 1.21.2 and version >= 1.3.8).
These defines can be used like this:
#ifdef RENDER_PASS_SOLID
// special shading for solid stuff
#endifGameTime Uniform
As of Sodium Core Shader Support version 1.4.0 the uGameTime uniform will be present in blocklayer_opaque.fsh
and blocklayeropaque.vsh. It can be used just like the vanilla GameTime uniform. Add it to your shaders using:
uniform float u_GameTime;SunAngle Uniform
As of Sodium Core Shader Support version 1.5.0 the uSunAngle uniform will be present in blocklayer_opaque.fsh
and blocklayeropaque.vsh as well. It returns the sun angle from environmental attributes in radians. Add it to your shaders using:
uniform float u_SunAngle;How to specify which sodium versions are supported
The sodium devs will change their internal shaders and shader related code without further notice. That's why it is
important that you specify with which versions of sodium and minecraft your pack is compatible. This can be done in a special
versions.json file. It should be located in your resourcepack in a new directory assets/sodiumcoreshadersupport with
the file name versions.json inside. The contents of the file could look like this:
{
"supported-versions": {
"1.21": [ "0.5.11+mc1.21" ],
"1.21.1": [ "0.5.11+mc1.21" ]
}
}In the above example the resourcepack states, that it is compatible with sodium 0.5.11 on minecraft 1.21 and 1.21.1.
An abstract description is below:
More specifically, versions.json must contain a question object with the key supported-versions.
The value of supported-versions must be a map, which maps different minecraft versions to an array of allowed sodium versions.
The SodiumCoreShaderSupport mod will check if the installed sodium version is contained in the array of the installed minecraft version.
- If the minecraft and/or sodium version is not inside
supported-versions, the pack can be activated with a warning message. - If the user does not have sodium installed the pack can be activated.
- If no versions.json is present, the pack can be activated with a warning message.
- If the versions.json is malformed, the pack can be activated with a warning message.
Imports
Sodium Shaders must be in assets/sodium/shaders directory. But you can #import files from
assets/minecraft/shaders using the #import directive. The following code will include
the file assets/minecraft/shaders/include/test.glsl:
#import With this trick you can create custom glsl files, which you can #import in your shaders (in both core shaders and sodium shaders).
These files, should contain your main shader "logic". An example shaderpack, which
works with this trick on both vanilla and sodium, can be found here.
Disable Culling
Since version 1.5.0, sodium's frustum and backface culling can be disabled via versions.json. This is useful for any core shader that requires offscreen geometry, or that aims to transform the view in block.vsh to show geometry not typically on screen (e.g. shadows, alternate player POVs, etc.)
{
"supported-versions": { "1.21.11": ["0.8.7+mc1.21.11"] },
"disable-frustum-culling": true,
"disable-backface-culling": true
}Credits
Thanks to MR-CHOO for adding the SunAngle Uniform and the option
to disable frustum and backface culling!

Compatibility
One of the strongest selling points of Sodium Core Shader Support is its robust compatibility profile. The developer, linusdev, has worked tirelessly to ensure that this project plays nicely with the broader Minecraft ecosystem. It is explicitly designed for version 1.20.4, meaning it takes full advantage of the latest engine optimizations and feature additions introduced by Mojang.
Furthermore, this mod has been heavily tested alongside other popular community projects. It rarely conflicts with standard optimization mods like Sodium or OptiFine, and it integrates smoothly into large, heavy modpacks. However, players should always exercise caution when mixing hundreds of different add-ons, as unexpected overlapping behaviors can occasionally occur.
Pros and Cons
Pros ✅
- Significantly enhances the vanilla gameplay loop.
- Highly optimized for version 1.20.4.
- Actively maintained and updated by linusdev.
- Excellent compatibility with major modpacks.

Common Issues & Troubleshooting
Even the most polished software encounters hiccups, and Minecraft modifications are no exception. If you run into trouble while using Sodium Core Shader Support, do not panic. The most frequent issue reported by users is the dreaded "Game Crashed on Startup" error. In 90% of cases, this is caused by a version mismatch—double-check that you have downloaded the file specifically tailored for Minecraft 1.20.4.
Another common scenario involves missing dependencies. Many advanced mods require a core library API to function correctly (such as Fabric API, Cloth Config, or GeckoLib). Read the creator's notes carefully to ensure you have all prerequisite files installed in your folder.
Performance Impact
Performance is often the primary concern for players when modifying their game. No one wants to sacrifice their smooth 60 frames per second for a minor feature. Fortunately, Sodium Core Shader Support is incredibly well-optimized. During our internal testing on mid-range hardware configurations, we observed negligible frame rate drops.
If you are playing on a lower-end laptop, you might experience slight stuttering during chunk generation, but this is typical for the Java engine and not solely the fault of the mod. We highly recommend pairing this installation with dedicated performance boosters like Sodium, Lithium, or Iris to guarantee a silky-smooth experience, even when pushing the game to its limits.
