NAME
matc - filament material tools
DESCRIPTION
matc is a command-line tool to compile material definition. Usages:
matc [options] <input-file>
Supported input formats:
Filament material definition (.mat)
OPTIONS
--help, -h
Print this message
--license
Print copyright and license information
--output, -o
Specify path to output file
--platform, -p
Shader family to generate: desktop, mobile or all (default)
--optimize-size, -S
Optimize generated shader code for size instead of just performance
--api, -a
Specify the target API: opengl (default), vulkan, metal, or all This flag can be repeated to
individually select APIs for inclusion:
matc --api opengl --api metal ...
--define, -D
Add a preprocessor define macro via <macro>=<value>. <value> defaults to 1 if omitted. Can be
repeated to specify multiple definitions:
matc -Dfoo=1 -Dbar -Dbuzz=100 ...
--reflect, -r
Reflect the specified metadata as JSON: parameters
--variant-filter=<filter>, -V <filter>
Filter out specified comma-separated variants:
directionalLighting, dynamicLighting, shadowReceiver, skinning, vsm, fog
This variant filter is merged with the filter from the material, if any
--version, -v
Print the material version number
Internal use and debugging only:
--optimize-none, -g
Disable all shader optimizations, for debugging
--preprocessor-only, -E
Optimize shaders by running only the preprocessor
--raw, -w
Compile a raw GLSL shader into a SPIRV binary chunk
--output-format, -f
Specify output format: blob (default) or header
--debug, -d
Generate extra data for debugging
--print, -t
Print generated shaders for debugging
