So was a little bored tonight, decided to see what I could do to display a vector using bifrost, which has a handy little create_arrow_strands I could leverage.
Results are not too bad, and could prob script up a little tool around it easily enough. Uses the worldMatrix[0] as an input directly.
And with a cleanup so default origins are IDMatrices, and a little connection script for selected, also showing making the vec local to it’s parent by plugging that into the originMtx.
