Commands¶

Main way of interacting with lazurite is with a command line interface, which can have different syntax, depending on the installation method

lazurite COMMAND [INPUTS ...] [ARGUMENTS ...]

lazurite.exe COMMAND [INPUTS ...] [ARGUMENTS ...]

python -m lazurite COMMAND [INPUTS ...] [ARGUMENTS ...]

Here is a cheatsheet of what each command does

Command	Description
unpack	Unpacks input materials
pack	Packs materials back into `material.bin` files
label	Adds a comment with debug information to plain text shaders (GLSL, ESSL, Metal)
clear	Clears compiled shaders in materials, while removing encryption
restore	Restores GLSL or SC source code from Android materials and varying.def.sc from any materials
build	Compiles all materials and shaders in a project
info	Displays useful information about input material
serialize	Generates minimal json from material bin files that can be used as merge source

unpack¶

lazurite unpack [MATERIALS ...] [--sort-flags] [--skip-shaders] [-o OUTPUT]

Argument	Description	Default
`--sort-flags`	Sorts variants and flags alphabeticaly
`--skip-shaders`	Don't unpack compiled shaders
`-o` `--output`	Output folder, where materials will be unpacked	current directory

Warning

This command won't unpack compiled shaders from encrypted materials (RTXStub)

This command unpacks input materials (material.bin files). You can specify multiple materials or folders with material files. By default, it will unpack into current working directory, but optional --output argument can be used to specify output directory instead. --sort-flags can be used to sort flags within variants and variants by flags, which might be useful when diffing unpacked materials. See material format for details on the unpacked material format.

Example usage

lazurite unpack Actor.bin folderWithMaterials/ RenderChunk.bin --sort-flags -o outputFolder/

This command will unpack Actor.bin, RenderChunk.bin and all materials in folderWithMaterials/ into the outputFolder/ while sorting their variants and flags.

pack¶

lazurite pack [MATERIALS ...] [-o OUTPUT]

Argument	Description	Default
`-o` `--output`	Output folder, where packed materials will be stored	current directory

This command packs unpacked input materials back into material.bin files. You can specify as an input:

Path to material.json file inside of unpacked material folder
Path to unpacked material folder (if it has material.json inside)
Path to a folder with unpacked materials (if it doesn't have material.json but each material inside of it does)

Multiple inputs can be specified at the same time. By default, materials will be packed into current working directory, but --output can be used to specify a different output directory.

Example usage

lazurite pack Actor/ folderWithMaterials/ RenderChunk/material.json -o outputFolder/

This command will pack Actor and RenderChunk materials as well as all materials from folderWithMaterials/ into the outputFolder/.

label¶

lazurite label [MATERIALS ...] [-o OUTPUT]

Argument	Description	Default
`-o` `--output`	Output folder, where labeled material bin files will be stored	current directory

Adds a comment with debug information at the top of shader programs. It's added to every plain text shader (ESSL, GLSL, Metal) inside of material.bin file. Here is an example of what it looks like:

// Shader Information:
// - Name: RenderChunk
// - Pass: Transparent
// - Platform: ESSL_310
// - Stage: Fragment
// - Variant: 0
// - Variant Supported: True
// - Variant Flags:
//    - Instancing: On
//    - RenderAsBillboards: On
//    - Seasons: Off

This information can be useful when using graphics debugger such as RenderDoc. As an input, you can specify multiple material.bin files or folders with them. --output can be used to specify output folder where labeled material.bin files will be stored (by default, it's the current working directory).

Example usage

lazurite label RenderChunk.material.bin folderWithMaterials/ -o outputFolder/

This command will label RenderChunk.material.bin and all materials from folderWithMaterials/ and save them as material.bin files in the outputFolder/.

clear¶

lazurite clear [MATERIALS ...] [-o OUTPUT]

Argument	Description	Default
`-o` `--output`	Output folder, where cleared material bin files will be stored	current directory

Wipes all compiled shaders, while removing encryption. This command can be useful when you need a light-weight merge source or when you want to compile RTX shader that shouldn't be encrypted. Note that if you unpack resulting material, its compiled shader files will be empty.

Example usage

lazurite clear RTXStub.material.bin -o outputFolder/

restore¶

lazurite restore [MATERIALS ...] [--timeout SECONDS] [--max-workers WORKERS] [--no-processing] [--merge-stages] [--split-passes] [-o OUTPUT]

Argument	Description	Default
`-o` `--output`	Output folder, where restored shaders will be stored	current directory
`--max-workers`	Maximum number of processes to use	CPU cores
`--timeout`	Maximum time allowed for slow search algorithm, in seconds	10
`--merge-stages`	Generates shader stages in a single file
`--split-passes`	Generates separate files for individual passes
`--no-processing`	Disable additional processing used for converting from GLSL to BGFX SC

Warning

This command won't restore shaders from encrypted materials (RTXStub)

Restoring latest Android materials

Starting from 1.21.31.05 release and 1.21.20.24 preview, restore command can no longer restore source code from Android materials since it's no longer shipped in material.bin files in a readable form. Instead, you can get it from older game versions by restoring their respective material.bin files or by downloading already restored code from mcbe codebase repository

Attempts to restore GLSL or BGFX SC source code from ESSL_300 or ESSL_310 materials (mainly used in Android) and varying.def.sc from any materials. It works by identifying the differences between individual shader variants and trying to find matching macro conditionals.

This command supports multiprocessing (utilizes multiple CPU cores) for faster restoring times and --max-workers argument can be used to specify max number of processes that will be created. Each process restores its own material.

When restoring macro conditionals, lazurite will first try to utilize fast algorithm, and if that fails, it will display slow search message in the console and try the slow search algorithm (brute-force), which has a time limit that can be set with --timeout. If slow search fails to find the conditional in provided time, it will display a not found message in the console and instead will use the best approximate solution it could find, which looks like this in code:

// Approximation, matches 256 cases out of 320
#if defined(ALPHA_TEST_PASS) || (defined(OPAQUE_PASS) && defined(UI_ENTITY__DISABLED))

When restoring BGFX SC source code, lazurite will also add // Attention! comment next to code that needs special attention, as it can't be edited automatically. It hints at a potential matrix multiplication or matrix element access.

For example:

vec4 jitterVertexPosition(vec3 worldPosition) {
    mat4 offsetProj = Proj;
    offsetProj[2][0] += SubPixelOffset.x; // Attention!
    offsetProj[2][1] -= SubPixelOffset.y; // Attention!
    return ((offsetProj) * (((View) * (vec4(worldPosition, 1.0f))))); // Attention!
}

Above code would have to be edited manually to look like this:

vec4 jitterVertexPosition(vec3 worldPosition) {
    mat4 offsetProj = Proj;
    #if BGFX_SHADER_LANGUAGE_GLSL
    offsetProj[2][0] += SubPixelOffset.x;
    offsetProj[2][1] -= SubPixelOffset.y;
    #else
    offsetProj[0][2] += SubPixelOffset.x;
    offsetProj[1][2] -= SubPixelOffset.y;
    #endif
    return mul(offsetProj, mul(View, vec4(worldPosition, 1.0f)));
}

However keep in mind that mul() can't be used for vector component-wise multiplication, and [x][y] syntax might also refer to accessing vector component of an array element instead of matrix element, in which case there is no need to change the index order.

Example usage

lazurite restore RenderChunk.material.bin folderWithMaterials/

This command will restore BGFX SC for RenderChunk.material.bin and for all materials from folderWithMaterials/ and save them in the current working directory.

build¶

lazurite build [PROJECTS ...] [--max-workers WORKERS] [--dxc DXC] [--shaderc SHADERC] [--dxc-args [ARGS ...]] [--shaderc-args [ARGS ...]] [-p [PROFILES ...]] [-d [DEFINES ...]] [-m [MATERIALS ...]] [-e [EXCLUDE ...]] [-o OUTPUT]

Argument	Description	Default
`-o` `--output`	Output folder, where compiled materials will be stored	project directory

This command will compile project in projects/pathTracer/ folder, with windows, android and preview active profiles and save the compiled materials in the output/ folder

Download DXC and SHADERC compilers

Shaderc is a cross platform compiler commonly used for compiling regular, non-rtx shaders.

Download: https://github.com/ddf8196/bgfx-mcbe/actions

Alternative download: https://github.com/veka0/bgfx-mcbe/releases/tag/binaries

DXC compiler is mainly used for compiling RTX shaders, as it only supports Direct3D.

Download: https://github.com/microsoft/DirectXShaderCompiler/releases

Running DXC on Linux

When trying to compile materials with DXC compiler on Linux you might encounter the following error:

./dxc error while loading shared libraries: libdxcompiler.so: cannot open shared object file: No such file or directory

It can be solved by prefixing lazurite command with LD_LIBRARY_PATH=<path to folder with libdxcompiler.so>

For example:

LD_LIBRARY_PATH=libs lazurite build myAwesomeShader/

Running SHADERC on Android (Termux)

If you wish to compile on Android, you have to copy shaderc into your termux home directory

cp path/to/shaderc ~/new/path/to/shaderc

Make it executable

chmod +x ~/new/path/to/shaderc

And reference it in future lazurite build commands

lazurite build --shaderc ~/new/path/to/shaderc myAwesomeShader/

You might also encounter the following error:

CANNOT LINK EXECUTABLE "/data/data/com.termux/files/home/shaderc": library "libc++_shared.so" not found: needed by main executable

Which can be solved by copying required file into your home directory

cp $PREFIX/lib/libc++_shared.so ~/

And referencing directory with your lib file in the lazurite command, by prefixing it with LD_LIBRARY_PATH=<path to folder with libc++_shared.so>

For example:

LD_LIBRARY_PATH=~/ lazurite build --shaderc ~/new/path/to/shaderc myAwesomeShader/

serialize¶

lazurite serialize [MATERIALS ...] [-o OUTPUT]

Argument	Description	Default
`-o` `--output`	Output folder, where generated `.material.json` files will be stored	current directory

Converts input material bin files into minimal json files, one file per material. Those files can be used as a merge source for build command, when compiling a project.

Generated json files only contain information that is necessary for compilation and nothing else, so they are quite lightweight. All material properties are sorted alphabetically which makes generated files invariant to changes in property sorting that occasionally occur with game updates. Sorting and small size makes this file format perfect for storing material merge source in version control systems such as GitHub.

Example usage

lazurite serialize RenderChunk.material.bin folderWithMaterials/ -o outputFolder/

This command will generate json files for RenderChunk.material.bin and all materials from folderWithMaterials/ and save them in the outputFolder/.
