Hi Ary,
I sent you a private message but thought I would reply here in hopes you will see my message (as I see your topic is a month old).
I have the same setup as you (8 body trackers with Vive Base Stations) + Manus Polygon, and I am having the same issue you had with the metahumans, where the spine, arms, and hands are all messed up. I am also not using the gloves. Is there any way you could take a screenshot of your bone mapping that made it work correctly?
I also would love to get the Polygon mapping working on the SK_Skeleton of the Mannequins, any chance you could help me get that set up?
I can always send you my email, instagram, or discord name, I’d love to chat with you about how you are using your setup, as I’m hoping to get into 3d Filmmaking (been in video production and film for 11+ years).
Thanks!
Nate
