hi michael,
I’m one of the guys who worked with wolff. For our project we told motive to send the skeleton as rigid bodys and then did some modifications to the plugin. Some new structs and also other stuff. I’m not really what exactly was changed since that was some other guys job. At the end we got the 21 bones Motive sends you in an array. The IDs keep changing, but the order in which they are send is always the same. The location data we got was pretty good, but the orientation was sometimes of by 90 degrees since the position Motive conciders 0/0/0 is different from what Unreal concinders 0/0/0 for that bone. So we added some offsets to every bone. What you see in the video is a gimbal lock. We avoided it by using Quats instead of Rotators. Only derictly before we apply the data to the Mannequin we go back to using an Rotator. Our project is due on May 31th. I will ask the guy who oversees us if I can upload it on an public git repository, after we are finished.
