Resolution Note:
When ProBuilder imports a mesh, it tests vertices against a very small value to see if it can safely consider them as coincident. This is done because ProBuilderize does not import mesh files, but rather converts existing mesh data.
In this case, vertices that were not intended to be coincident were incorrectly flagged due to the import scale placing discrete vertices in the same position. This is what caused the black triangles.
