.SS "Supported input formats:"
.IP
Filament material definition (.mat)
.SH OPTIONS
.HP
\fB\-\-help\fR, \fB\-h\fR
.IP
Print this message
.HP
\fB\-\-license\fR
.IP
Print copyright and license information
.HP
\fB\-\-output\fR, \fB\-o\fR
.IP
Specify path to output file
.HP
\fB\-\-platform\fR, \fB\-p\fR
.IP
Shader family to generate: desktop, mobile or all (default)
.HP
\fB\-\-optimize\-size\fR, \fB\-S\fR
.IP
Optimize generated shader code for size instead of just performance
.HP
\fB\-\-api\fR, \fB\-a\fR
.IP
Specify the target API: opengl (default), vulkan, metal, or all
This flag can be repeated to individually select APIs for inclusion:
.IP
matc \fB\-\-api\fR opengl \fB\-\-api\fR metal ...
.HP
\fB\-\-define\fR, \fB\-D\fR
.IP
Add a preprocessor define macro via <macro>=<value>. <value> defaults to 1 if omitted.
Can be repeated to specify multiple definitions:
.IP
matc \fB\-Dfoo\fR=\fI\,1\/\fR \fB\-Dbar\fR \fB\-Dbuzz\fR=\fI\,100\/\fR ...
.HP
\fB\-\-reflect\fR, \fB\-r\fR
.IP
Reflect the specified metadata as JSON: parameters
.HP
\fB\-\-variant\-filter=\fR<filter>, \fB\-V\fR <filter>
.IP
Filter out specified comma\-separated variants:
.IP
directionalLighting, dynamicLighting, shadowReceiver, skinning, vsm, fog
.IP
This variant filter is merged with the filter from the material, if any
.HP
\fB\-\-version\fR, \fB\-v\fR
.IP
Print the material version number
