Shader compiler used to generate player data shader variants.
In Unity, shader programs are written in a variant of HLSL language.
Each platform supports one or multiple graphics APIs. For example, Vulkan and Direct3D 12 are both supported in Windows.
When building a standalone player, for each supported graphics API, Unity runs a corresponding shader compiler which generates the shader variants and cross-compiles the shader snippet into the shading language natively supported by the graphics API.
