Entry point to create an approximate USD Preview Surface network from a Cycles node graph. Due to the limited nodes in the USD Preview Surface specification, only the following nodes are supported:

UVMap
Texture Coordinate
Image Texture
Principled BSDF More may be added in the future.

Parameters

default_uv used as the default UV set name sampled by the primvar reader shaders generated for image texture nodes that don't have an attached UVMap node.
