I'm using Optitrack Motive for my MOCAP - exporting this as a FBX file and importing it into 3DXchange for use on a non-standard Character Creator avatar. When I initially import my MOCAP into 3DXchange my RootNode bone is rotated and when I select Active T-Pose the RootNode bone rotates to the correct position but the skeletons left foot moves behind the right foot. If I rotate the RootNode bone to the correct position select active T-pose I still have the same issue. Any ideas on what I'm doing wrong?

Hi annamation,

A couple screen shots would be useful in trying to help you with this, I think I know what you're seeing though so I'll offer this advice.

You'll want to correct the Tpose before setting the bones has been my experience with 3DX.  So in your case I would rotate the avatar and manually adjust the limbs etc. to a good Tpose, then set the bones and hit active to see if it needs more tweaking.  Once you have a good Tpose then save it so you can import more of your mocap without having to deal with the Tpose setup each time.  Ideally it would be better to see if your mocap program can set a standard Tpose that will work in 3DX.

There's a bunch of 3DX tutorials on YouTube [HERE] that should help, even the older ones with 3DX5 show the basic concept of adjusting the Tpose.
