I've come across an issue with the files that are exported from iPi Mocap Studio. There are random rotations on the hip in x and z which cause the whole body to pivot around the hips over a few frames. I've attached an image which shows the graph and I've overlayed the skeleton so you can see how much the whole body shifts over a few frames. If I scrub through the same frame range in Mocap Studio, I do not see the feet or hips move like they do in the exported file.
It may not look like much here, but when I retarget the animation to a character it's very noticable and takes a lot of work to remove. I've tried a gimbal filter, but that does not work. I've exported as a bvh and an fbx, but both are the same.
Any ideas what may be causing this and how to prevent it from happening?
Thanks!
