troubles with orientation of c3d

[VJLW]

I' m having troubles importing c3d data from arena expression in facerobot(softimage 2011).When I open tha file, the markers are facing -x. Seems that with this orientation i cannot apply the movement correctl. In all videos that i saw the face markers are facing -Z, and the axis match perfect between expression and softimage without troubles.

Someone have similar issues?What i' m doing wrong?

any advices ?

thanks in advance

It almost sounds like your ground plane was rotated 90 degrees when you originally calibrated the volume. I'd recalibrate, make sure you set the ground plane appropriately, and recapture a small bit of data to test.
