Bvh import into Genesis back to front

I imported a bvh exported from fragMOTION, everything seems to be fine except that the figure animates back to front. The Genesis's chest is now it's back and it's backside is now where its groin is. The legs and arms are like as if they were attached backwards. It's like all the bones are the wrong way round and need to be rotated 90 degrees on their X or Y axis. Is there anyway to rectify this? Twisting the bones messes up the figure.

    The axis order is likely erroneous and/or the figure in fragMOTION uses a left handed system (check in the options).
    A simple fix may be to rotate Genesis 180 Y degrees before importing the BVH.

    Thanks, rotating the Genesis figure on its Y axis 180 degrees did have some limited effect, but it appears some of the joints on the limbs are messed up too, some are backwards. The rotation order of the bones seem to be messed up. I'm not sure how to go about fixing this and if it's just some bones or all of them.

    I have a BVH exported from Biped that loads correctly in DS, the rotation order is as follows:

          }
         }
        }
       }
      }
     }
    
    They are Z,X Y for arms too. Hopefully that will help you enough.
