HLSL pragma target command reference

Reference for the shader models Unity uses, and the combination of pragma values that each corresponds to.

Here is the list of shader models that Unity uses, and the combination of 
#pragma require
values that each corresponds to.
注意
Unity's shader models are similar to DirectX shader models and OpenGL version requirements, but they do not correspond exactly. Read the descriptions carefully to ensure that you understand the differences.

Notes:
  • In the DirectX definitions, shader model 4.0 includes 
    mrt8
    , and shader model 5.0 includes 
    interpolators32
    and 
    cubearray
    . Unity does not include these, for broader compatibility. To require these features, use an explicit 
    #pragma require
    directive.
  • If you use a target that requires 
    geometry
    but your shader does not define a geometry stage, Unity removes 
    geometry
    from the list of requirements at compile time.
  • If you use a target that requires 
    tessellation
    but your shader does not define a hull or domain stage, Unity removes 
    tessellation
    from the list of requirements at compile time.
