Whether a triangle is considered forward or backward facing is
determined by the winding order of the vertices, so you also need to
swap the ordering on your other face.
Alternatively, disable the back face culling renderstate in your
material or frame graph. This is enabled by default for performance
reasons but if you explicitly need to see the backfaces this can be
adjusted.
Cheers,
Sean
