Fully qualified name: usdex::core::defineGlassPreviewMaterial

pxr::UsdShadeMaterial usdex::core::defineGlassPreviewMaterial(

pxr::UsdStagePtr stage,

const pxr::SdfPath &path,

const pxr::GfVec3f &color,

const float indexOfRefraction = 1.5f,

const float roughness = 0.02f,

const float opacity = 0.2f,

)

Defines a Glass PBR UsdShadeMaterial driven by a UsdPreviewSurface shader network for the universal render context.

The input parameters reflect a subset of the UsdPreviewSurface specification commonly used when authoring glass materials.

Note

To make the color take effect, opacity must be used to make the material sufficiently opaque.

Parameters:

• stage – The stage on which to define the Material

• path – The absolute prim path at which to define the Material

• color – The color of the Material

• indexOfRefraction – The Index of Refraction to set, minimum 1.0; suggested maximum 4.0

• roughness – The Roughness Amount to set, 0.0-1.0 range where 1.0 = flat and 0.0 = glossy

• opacity – The Opacity Amount to set, 0.0-1.0 range where 1.0 = opaque and 0.0 = invisible

Returns:

The newly defined UsdShadeMaterial. Returns an Invalid object on error.
