Compiling to Assets

Compiling project resources into assets is done using the assetc command-line tool.

Upon invocation, it will scan the input folder and compile all resources in a supported format to the output folder. Files in an unsupported format are copied unmodified to the output folder.

It is very important that you treat the compiled output folder as entirely disposable and only ever perform modifications in the input folder. Output assets will be different for each platform you compile to.

Again, do not ever work in the assets folder.

If you are unclear on the resources/assets distinction see Resources & Assets.

Command-Line

assetc <input> [output PATH] [-daemon] [-platform PLATFORM] [-api API] [-defines DEFINES] [-job COUNT]
       [-toolchain PATH] [-progress] [-log_to_std_out] [-debug] [-quiet] [-verbose]
OptionShortcutDescription
-inputInput project resources folder.
-outputOutput compiled assets folder. If unspecified, the input folder path suffixed with _compiled is used.
-daemon-dRun the compiler in daemon mode. The compiler will constantly monitor the input folder and compile its content as it is modified.
-platform-pPlatform to target.
-apiGraphics API to target. Some platforms (eg. PC) might support multiple graphics API (DX11, DX12, GL, …).
-defines-DSemicolon separated defines to pass to the shader compiler (eg. FLAG;VALUE=2).
-job-jMaximum number of parallel job (0 - automatic).
-toolchain-tPath to the toolchain folder.
-progressOutput progress to the standard output.
-log_to_std_out-lLog errors to the standard output.
-debugCompile in debug mode (eg. output debug informations in shader).
-quiet-qDisable all build information but errors.
-verbose-vOutput additional information about the compilation process.

Note: When run in daemon mode assetc will not exit after its initial run and will keep watching the input folder. When a resource is modified it will automatically be compiled to the output folder.
