So this video is doing the rounds, impressive that it unofficially has great support for full axis / skeleton / whatever the right term is, to allow for 6DOF.
I am still having zero luck with VorpX, but I am inspired to persevere and try again. Although with 3.14 and Gen12 / Vulkan round the corner, that might be the ideal time.
Also just saw this setup guide for 3.11 and 3.12 and the 8KX. And references the good work by @risa2000
