This tool will create, hook up and autocomplete the file paths for the nodes you specify. Computes UV co-ordinates projected along a single axis, derived from the position of an object, and generates a mask relative to the projection axis. Because of this there are a few rough edges. The Component Builder tool automates or enforces various best practices (this is especially useful for artists and studios new to USD): Sets up the geometry as a payload so the artist can easily unload it, and still see a bounding box in the viewport. Returns vertex indices of each face of a tetrahedron. returns the displaced surface position, normal, and displacement amount. The node chains representing the surface and displacement shaders feed into Output nodes (parameters on the Output node control what kind of shader its inputs create).
