bool usdex::core::addPrimvarShaderToPreviewMaterial(

pxr::UsdShadeMaterial &material,

const std::string &surfaceInputName,

const std::string &primvarName,

const pxr::VtValue &fallbackValue = pxr::VtValue(),

)

Adds a primvar reader shader to the material prim and connects it to a surface input.

It is expected that the material was created by definePreviewMaterial()

Parameters:

• material – The material prim

• surfaceInputName – The name of the input on the surface shader (not including the inputs: prefix, eg. diffuseColor)

• primvarName – The name of the primvar to read (not including the primvars: prefix, eg. paintColor)

• fallbackValue – An optional fallback value to use if the primvar is not found

Returns:

Whether or not the primvar shader was added to the material
