//! This builder is the forerunner of the shader build pipeline.
|
|
//! It will perform the first 3 transformations on shader files (.shader) and AZSL-containing files (.azsl/.azsli/.srgi)
|
|
//! Which are: [prepend common header -> preprocess -> transpile AZSL to HLSL & reflect all shader program properties of interest into json files]
|
|
//! The next builders in the chain: SRG/Shader/Variant, will consume the output products of this builder, without having to re-run Azslc nor Mcpp
|
|
//! Note that the output products are not traditional product assets that will be used by the game project.
|
|
//! They are artifacts that are produced once, cached, and used later by other AssetBuilders as a way to centralize build organization.
