Hi,
    When I am trying to convert the dae file into bones, I got the following error " java.lang.IllegalArgumentException: Transforms that have non-rotational matrices are not supported."
    The workflow is: I used motionBuilder to read in a C3d file that contains a set of animations, and export a skeleton into Maya, then I bind the skeleton with a character that I made, and export it into the dae format.
     Is it because the motionbuilder does the animation without using the rotation matrix?? if so how can I fix it??
Thanks
