Hi all!! i have worked on our DIY motion capture for past few weeks, bought the parts needed and assemble it together and its went pretty well!! only for a couple of days tho 
. But after doing some testing we found out that the hips rotation are very off the expectation.
here’s the video on the issue.
we got the project from this repo .
we assume the cause are either the bones, the sensors, the animGraph, or the Blueprints.
any suggestion??
