Hi,
just a very short question:
Is there an XPresso node equivalent to the HPBToMatrix() function from the SDK? And if not, how could one create an XPresso setup that performs this calculation?
Thanks & Greetings,
Jack

Damn, I was hoping there would be an XPresso-only solution.
But can't I just use this?
